Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624876, here are decompositions:

47 + 31624829 = 31624876
113 + 31624763 = 31624876
137 + 31624739 = 31624876
233 + 31624643 = 31624876
263 + 31624613 = 31624876
317 + 31624559 = 31624876
419 + 31624457 = 31624876
509 + 31624367 = 31624876

Showing the first eight; more decompositions exist.
