Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524992, here are decompositions:

3 + 31524989 = 31524992
199 + 31524793 = 31524992
229 + 31524763 = 31524992
271 + 31524721 = 31524992
349 + 31524643 = 31524992
523 + 31524469 = 31524992
661 + 31524331 = 31524992
691 + 31524301 = 31524992

Showing the first eight; more decompositions exist.
