Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625396, here are decompositions:

3 + 31625393 = 31625396
13 + 31625383 = 31625396
337 + 31625059 = 31625396
457 + 31624939 = 31625396
547 + 31624849 = 31625396
613 + 31624783 = 31625396
643 + 31624753 = 31625396
757 + 31624639 = 31625396

Showing the first eight; more decompositions exist.
