Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524550, here are decompositions:

17 + 31524533 = 31524550
41 + 31524509 = 31524550
131 + 31524419 = 31524550
257 + 31524293 = 31524550
293 + 31524257 = 31524550
353 + 31524197 = 31524550
383 + 31524167 = 31524550
389 + 31524161 = 31524550

Showing the first eight; more decompositions exist.
