Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588554, here are decompositions:

31 + 31588523 = 31588554
61 + 31588493 = 31588554
71 + 31588483 = 31588554
83 + 31588471 = 31588554
113 + 31588441 = 31588554
197 + 31588357 = 31588554
223 + 31588331 = 31588554
233 + 31588321 = 31588554

Showing the first eight; more decompositions exist.
