Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625446, here are decompositions:

53 + 31625393 = 31625446
389 + 31625057 = 31625446
467 + 31624979 = 31625446
617 + 31624829 = 31625446
647 + 31624799 = 31625446
683 + 31624763 = 31625446
773 + 31624673 = 31625446
887 + 31624559 = 31625446

Showing the first eight; more decompositions exist.
