Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541524, here are decompositions:

17 + 31541507 = 31541524
41 + 31541483 = 31541524
107 + 31541417 = 31541524
227 + 31541297 = 31541524
257 + 31541267 = 31541524
281 + 31541243 = 31541524
383 + 31541141 = 31541524
503 + 31541021 = 31541524

Showing the first eight; more decompositions exist.
