Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625016, here are decompositions:

37 + 31624979 = 31625016
89 + 31624927 = 31625016
109 + 31624907 = 31625016
167 + 31624849 = 31625016
179 + 31624837 = 31625016
233 + 31624783 = 31625016
263 + 31624753 = 31625016
277 + 31624739 = 31625016

Showing the first eight; more decompositions exist.
