Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625068, here are decompositions:

11 + 31625057 = 31625068
29 + 31625039 = 31625068
89 + 31624979 = 31625068
239 + 31624829 = 31625068
269 + 31624799 = 31625068
509 + 31624559 = 31625068
521 + 31624547 = 31625068
557 + 31624511 = 31625068

Showing the first eight; more decompositions exist.
