Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624888, here are decompositions:

59 + 31624829 = 31624888
89 + 31624799 = 31624888
107 + 31624781 = 31624888
149 + 31624739 = 31624888
227 + 31624661 = 31624888
257 + 31624631 = 31624888
431 + 31624457 = 31624888
521 + 31624367 = 31624888

Showing the first eight; more decompositions exist.
