Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625050, here are decompositions:

11 + 31625039 = 31625050
71 + 31624979 = 31625050
251 + 31624799 = 31625050
269 + 31624781 = 31625050
311 + 31624739 = 31625050
389 + 31624661 = 31625050
419 + 31624631 = 31625050
491 + 31624559 = 31625050

Showing the first eight; more decompositions exist.
