Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625226, here are decompositions:

47 + 31625179 = 31625226
79 + 31625147 = 31625226
167 + 31625059 = 31625226
389 + 31624837 = 31625226
397 + 31624829 = 31625226
419 + 31624807 = 31625226
443 + 31624783 = 31625226
463 + 31624763 = 31625226

Showing the first eight; more decompositions exist.
