Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625054, here are decompositions:

103 + 31624951 = 31625054
127 + 31624927 = 31625054
193 + 31624861 = 31625054
271 + 31624783 = 31625054
313 + 31624741 = 31625054
337 + 31624717 = 31625054
457 + 31624597 = 31625054
463 + 31624591 = 31625054

Showing the first eight; more decompositions exist.
