Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537256, here are decompositions:

13 + 31537243 = 31537256
103 + 31537153 = 31537256
109 + 31537147 = 31537256
229 + 31537027 = 31537256
313 + 31536943 = 31537256
409 + 31536847 = 31537256
433 + 31536823 = 31537256
463 + 31536793 = 31537256

Showing the first eight; more decompositions exist.
