Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625392, here are decompositions:

11 + 31625381 = 31625392
41 + 31625351 = 31625392
89 + 31625303 = 31625392
131 + 31625261 = 31625392
353 + 31625039 = 31625392
563 + 31624829 = 31625392
593 + 31624799 = 31625392
653 + 31624739 = 31625392

Showing the first eight; more decompositions exist.
