Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625554, here are decompositions:

17 + 31625537 = 31625554
47 + 31625507 = 31625554
101 + 31625453 = 31625554
173 + 31625381 = 31625554
251 + 31625303 = 31625554
293 + 31625261 = 31625554
647 + 31624907 = 31625554
773 + 31624781 = 31625554

Showing the first eight; more decompositions exist.
