Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617758, here are decompositions:

61 + 31617697 = 31617758
79 + 31617679 = 31617758
127 + 31617631 = 31617758
199 + 31617559 = 31617758
229 + 31617529 = 31617758
349 + 31617409 = 31617758
379 + 31617379 = 31617758
397 + 31617361 = 31617758

Showing the first eight; more decompositions exist.
