Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625046, here are decompositions:

7 + 31625039 = 31625046
67 + 31624979 = 31625046
107 + 31624939 = 31625046
139 + 31624907 = 31625046
197 + 31624849 = 31625046
239 + 31624807 = 31625046
263 + 31624783 = 31625046
283 + 31624763 = 31625046

Showing the first eight; more decompositions exist.
