Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524514, here are decompositions:

5 + 31524509 = 31524514
257 + 31524257 = 31524514
317 + 31524197 = 31524514
347 + 31524167 = 31524514
353 + 31524161 = 31524514
467 + 31524047 = 31524514
491 + 31524023 = 31524514
503 + 31524011 = 31524514

Showing the first eight; more decompositions exist.
