Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537288, here are decompositions:

17 + 31537271 = 31537288
59 + 31537229 = 31537288
137 + 31537151 = 31537288
191 + 31537097 = 31537288
239 + 31537049 = 31537288
467 + 31536821 = 31537288
557 + 31536731 = 31537288
569 + 31536719 = 31537288

Showing the first eight; more decompositions exist.
