Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537732, here are decompositions:

11 + 31537721 = 31537732
41 + 31537691 = 31537732
101 + 31537631 = 31537732
173 + 31537559 = 31537732
251 + 31537481 = 31537732
263 + 31537469 = 31537732
419 + 31537313 = 31537732
461 + 31537271 = 31537732

Showing the first eight; more decompositions exist.
