A067035 n sets a new record for the number of integers k such that n = k + reverse(k).
0, 22, 33, 44, 55, 66, 77, 88, 99, 1111, 2552, 2662, 2772, 2882, 2992, 3663, 3773, 3883, 3993, 4774, 4884, 4994, 5885, 5995, 6886, 6996, 7887, 7997, 8888, 8998, 9889, 9999, 199991, 258852, 259952, 268862, 269962, 278872, 279972, 288882, 289982

Examples
33 belongs to the sequence because for three integers k (cf. A067032) we have 33 = k + reverse(k) and for m < 33 there are at most two integers j such that m = j + reverse(j).
