Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529626, here are decompositions:

3 + 31529623 = 31529626
59 + 31529567 = 31529626
179 + 31529447 = 31529626
347 + 31529279 = 31529626
353 + 31529273 = 31529626
383 + 31529243 = 31529626
659 + 31528967 = 31529626
773 + 31528853 = 31529626

Showing the first eight; more decompositions exist.
