Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537598, here are decompositions:

7 + 31537591 = 31537598
271 + 31537327 = 31537598
331 + 31537267 = 31537598
397 + 31537201 = 31537598
571 + 31537027 = 31537598
607 + 31536991 = 31537598
661 + 31536937 = 31537598
727 + 31536871 = 31537598

Showing the first eight; more decompositions exist.
