Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524658, here are decompositions:

17 + 31524641 = 31524658
71 + 31524587 = 31524658
89 + 31524569 = 31524658
149 + 31524509 = 31524658
239 + 31524419 = 31524658
401 + 31524257 = 31524658
461 + 31524197 = 31524658
491 + 31524167 = 31524658

Showing the first eight; more decompositions exist.
