Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624846, here are decompositions:

17 + 31624829 = 31624846
47 + 31624799 = 31624846
83 + 31624763 = 31624846
107 + 31624739 = 31624846
173 + 31624673 = 31624846
233 + 31624613 = 31624846
389 + 31624457 = 31624846
479 + 31624367 = 31624846

Showing the first eight; more decompositions exist.
