Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625572, here are decompositions:

5 + 31625567 = 31625572
179 + 31625393 = 31625572
191 + 31625381 = 31625572
269 + 31625303 = 31625572
311 + 31625261 = 31625572
593 + 31624979 = 31625572
743 + 31624829 = 31625572
773 + 31624799 = 31625572

Showing the first eight; more decompositions exist.
