Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625076, here are decompositions:

17 + 31625059 = 31625076
19 + 31625057 = 31625076
37 + 31625039 = 31625076
97 + 31624979 = 31625076
137 + 31624939 = 31625076
149 + 31624927 = 31625076
227 + 31624849 = 31625076
239 + 31624837 = 31625076

Showing the first eight; more decompositions exist.
