Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624966, here are decompositions:

59 + 31624907 = 31624966
137 + 31624829 = 31624966
167 + 31624799 = 31624966
227 + 31624739 = 31624966
293 + 31624673 = 31624966
353 + 31624613 = 31624966
419 + 31624547 = 31624966
509 + 31624457 = 31624966

Showing the first eight; more decompositions exist.
