Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625350, here are decompositions:

47 + 31625303 = 31625350
89 + 31625261 = 31625350
293 + 31625057 = 31625350
311 + 31625039 = 31625350
443 + 31624907 = 31625350
521 + 31624829 = 31625350
569 + 31624781 = 31625350
587 + 31624763 = 31625350

Showing the first eight; more decompositions exist.
