Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625106, here are decompositions:

47 + 31625059 = 31625106
67 + 31625039 = 31625106
127 + 31624979 = 31625106
167 + 31624939 = 31625106
179 + 31624927 = 31625106
199 + 31624907 = 31625106
257 + 31624849 = 31625106
269 + 31624837 = 31625106

Showing the first eight; more decompositions exist.
