Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502126, here are decompositions:

13 + 31502113 = 31502126
43 + 31502083 = 31502126
277 + 31501849 = 31502126
307 + 31501819 = 31502126
367 + 31501759 = 31502126
457 + 31501669 = 31502126
727 + 31501399 = 31502126
739 + 31501387 = 31502126

Showing the first eight; more decompositions exist.
