Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629738, here are decompositions:

59 + 8629679 = 8629738
101 + 8629637 = 8629738
389 + 8629349 = 8629738
569 + 8629169 = 8629738
599 + 8629139 = 8629738
659 + 8629079 = 8629738
839 + 8628899 = 8629738
881 + 8628857 = 8629738

Showing the first eight; more decompositions exist.
