Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625116, here are decompositions:

59 + 31625057 = 31625116
137 + 31624979 = 31625116
317 + 31624799 = 31625116
353 + 31624763 = 31625116
443 + 31624673 = 31625116
503 + 31624613 = 31625116
557 + 31624559 = 31625116
569 + 31624547 = 31625116

Showing the first eight; more decompositions exist.
