Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625110, here are decompositions:

53 + 31625057 = 31625110
71 + 31625039 = 31625110
131 + 31624979 = 31625110
281 + 31624829 = 31625110
311 + 31624799 = 31625110
347 + 31624763 = 31625110
449 + 31624661 = 31625110
467 + 31624643 = 31625110

Showing the first eight; more decompositions exist.
