Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522588, here are decompositions:

5 + 31522583 = 31522588
47 + 31522541 = 31522588
59 + 31522529 = 31522588
137 + 31522451 = 31522588
257 + 31522331 = 31522588
311 + 31522277 = 31522588
347 + 31522241 = 31522588
359 + 31522229 = 31522588

Showing the first eight; more decompositions exist.
