Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588552, here are decompositions:

29 + 31588523 = 31588552
59 + 31588493 = 31588552
89 + 31588463 = 31588552
113 + 31588439 = 31588552
239 + 31588313 = 31588552
353 + 31588199 = 31588552
449 + 31588103 = 31588552
491 + 31588061 = 31588552

Showing the first eight; more decompositions exist.
