Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625152, here are decompositions:

3 + 31625149 = 31625152
5 + 31625147 = 31625152
113 + 31625039 = 31625152
173 + 31624979 = 31625152
353 + 31624799 = 31625152
389 + 31624763 = 31625152
479 + 31624673 = 31625152
491 + 31624661 = 31625152

Showing the first eight; more decompositions exist.
