A341013 The cumulative sum of the prime digits so far in the sequence and the cumulative sum of the nonprime digits so far differ by n for all a(n) values.
1, 3, 12, 16, 10, 34, 43, 56, 65, 78, 87, 100, 236, 258, 263, 285, 304, 326, 340, 359, 362, 395, 403, 430, 447, 474, 506, 528, 539, 560, 582, 593, 605, 623, 632, 650, 708, 744, 780, 807, 825, 852, 870, 935, 953, 1000, 1112, 1121, 1145, 1154, 1167, 1176

Examples
Say that the current sequence is S, the cumulative sum at any moment of the prime digits of S is P, the cumulative sum at any moment of the nonprime digits of S is N and the absolute difference |P-N| is D. We would then have: S = 1, 3, 12, 16, 10, 34, 43, 56, 65, 78, 87, 100,... P = 0 3 5 5 5 8 11 16 21 28 35 35 N = 1 1 2 9 10 14 18 24 30 38 46 47 D = 1 2 3 4 5 6 7 8 9 10 11 12 <-- this is = n
