Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588932, here are decompositions:

5 + 31588927 = 31588932
223 + 31588709 = 31588932
233 + 31588699 = 31588932
239 + 31588693 = 31588932
409 + 31588523 = 31588932
439 + 31588493 = 31588932
449 + 31588483 = 31588932
461 + 31588471 = 31588932

Showing the first eight; more decompositions exist.
