Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625536, here are decompositions:

29 + 31625507 = 31625536
83 + 31625453 = 31625536
233 + 31625303 = 31625536
389 + 31625147 = 31625536
479 + 31625057 = 31625536
557 + 31624979 = 31625536
773 + 31624763 = 31625536
797 + 31624739 = 31625536

Showing the first eight; more decompositions exist.
