Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592588, here are decompositions:

31 + 31592557 = 31592588
37 + 31592551 = 31592588
151 + 31592437 = 31592588
199 + 31592389 = 31592588
211 + 31592377 = 31592588
241 + 31592347 = 31592588
277 + 31592311 = 31592588
331 + 31592257 = 31592588

Showing the first eight; more decompositions exist.
