Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625308, here are decompositions:

5 + 31625303 = 31625308
47 + 31625261 = 31625308
251 + 31625057 = 31625308
269 + 31625039 = 31625308
401 + 31624907 = 31625308
479 + 31624829 = 31625308
509 + 31624799 = 31625308
569 + 31624739 = 31625308

Showing the first eight; more decompositions exist.
