Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625368, here are decompositions:

17 + 31625351 = 31625368
107 + 31625261 = 31625368
311 + 31625057 = 31625368
389 + 31624979 = 31625368
461 + 31624907 = 31625368
569 + 31624799 = 31625368
587 + 31624781 = 31625368
809 + 31624559 = 31625368

Showing the first eight; more decompositions exist.
