Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617386, here are decompositions:

7 + 31617379 = 31617386
13 + 31617373 = 31617386
103 + 31617283 = 31617386
313 + 31617073 = 31617386
337 + 31617049 = 31617386
373 + 31617013 = 31617386
457 + 31616929 = 31617386
499 + 31616887 = 31617386

Showing the first eight; more decompositions exist.
