Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625996, here are decompositions:

43 + 31625953 = 31625996
79 + 31625917 = 31625996
223 + 31625773 = 31625996
229 + 31625767 = 31625996
349 + 31625647 = 31625996
379 + 31625617 = 31625996
397 + 31625599 = 31625996
433 + 31625563 = 31625996

Showing the first eight; more decompositions exist.
