Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588584, here are decompositions:

23 + 31588561 = 31588584
61 + 31588523 = 31588584
101 + 31588483 = 31588584
113 + 31588471 = 31588584
227 + 31588357 = 31588584
233 + 31588351 = 31588584
263 + 31588321 = 31588584
271 + 31588313 = 31588584

Showing the first eight; more decompositions exist.
