Comments

A129363(n) is the number of partitions of 2*n into the sum of two twin primes.

Conjecture: Sequence is finite and complete with last term 2103.

No further term between 2103 and 26000 - [From R. J. Mathar, Oct 24 2010]

Examples

			A129363(8) = A129363(9) = A129363(10) = 2 (the partitions are 16 = 3+13 = 5+11, 18 = 5+13 = 7+11, 20 = 3+17 = 7+13), hence 9 is in the sequence.
A129363(197) = A129363(198) = A129363(199) = 1 (the partitions are 394 = 197+197, 396 = 197+199, 398 = 199+199), hence 198 is in the sequence.
A129363(47) = A129363(48) = A129363(49) = 0 (there are no partitions of 94, 96, 98), hence 48 is in the sequence.
