Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625264, here are decompositions:

3 + 31625261 = 31625264
313 + 31624951 = 31625264
337 + 31624927 = 31625264
457 + 31624807 = 31625264
523 + 31624741 = 31625264
547 + 31624717 = 31625264
673 + 31624591 = 31625264
757 + 31624507 = 31625264

Showing the first eight; more decompositions exist.
