Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625416, here are decompositions:

5 + 31625411 = 31625416
23 + 31625393 = 31625416
113 + 31625303 = 31625416
269 + 31625147 = 31625416
359 + 31625057 = 31625416
509 + 31624907 = 31625416
587 + 31624829 = 31625416
617 + 31624799 = 31625416

Showing the first eight; more decompositions exist.
