Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31558510, here are decompositions:

41 + 31558469 = 31558510
47 + 31558463 = 31558510
131 + 31558379 = 31558510
173 + 31558337 = 31558510
227 + 31558283 = 31558510
257 + 31558253 = 31558510
281 + 31558229 = 31558510
311 + 31558199 = 31558510

Showing the first eight; more decompositions exist.
