Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625684, here are decompositions:

3 + 31625681 = 31625684
31 + 31625653 = 31625684
37 + 31625647 = 31625684
67 + 31625617 = 31625684
283 + 31625401 = 31625684
421 + 31625263 = 31625684
733 + 31624951 = 31625684
757 + 31624927 = 31625684

Showing the first eight; more decompositions exist.
