Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625074, here are decompositions:

17 + 31625057 = 31625074
167 + 31624907 = 31625074
293 + 31624781 = 31625074
311 + 31624763 = 31625074
401 + 31624673 = 31625074
431 + 31624643 = 31625074
443 + 31624631 = 31625074
461 + 31624613 = 31625074

Showing the first eight; more decompositions exist.
