Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535726, here are decompositions:

223 + 31535503 = 31535726
307 + 31535419 = 31535726
349 + 31535377 = 31535726
463 + 31535263 = 31535726
499 + 31535227 = 31535726
613 + 31535113 = 31535726
619 + 31535107 = 31535726
643 + 31535083 = 31535726

Showing the first eight; more decompositions exist.
