Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625212, here are decompositions:

173 + 31625039 = 31625212
233 + 31624979 = 31625212
383 + 31624829 = 31625212
431 + 31624781 = 31625212
449 + 31624763 = 31625212
569 + 31624643 = 31625212
599 + 31624613 = 31625212
653 + 31624559 = 31625212

Showing the first eight; more decompositions exist.
