Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625256, here are decompositions:

107 + 31625149 = 31625256
109 + 31625147 = 31625256
197 + 31625059 = 31625256
199 + 31625057 = 31625256
277 + 31624979 = 31625256
317 + 31624939 = 31625256
349 + 31624907 = 31625256
419 + 31624837 = 31625256

Showing the first eight; more decompositions exist.
