Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625092, here are decompositions:

53 + 31625039 = 31625092
113 + 31624979 = 31625092
263 + 31624829 = 31625092
293 + 31624799 = 31625092
311 + 31624781 = 31625092
353 + 31624739 = 31625092
419 + 31624673 = 31625092
431 + 31624661 = 31625092

Showing the first eight; more decompositions exist.
