Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625464, here are decompositions:

11 + 31625453 = 31625464
53 + 31625411 = 31625464
71 + 31625393 = 31625464
83 + 31625381 = 31625464
113 + 31625351 = 31625464
317 + 31625147 = 31625464
557 + 31624907 = 31625464
683 + 31624781 = 31625464

Showing the first eight; more decompositions exist.
