Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617494, here are decompositions:

37 + 31617457 = 31617494
211 + 31617283 = 31617494
241 + 31617253 = 31617494
313 + 31617181 = 31617494
421 + 31617073 = 31617494
577 + 31616917 = 31617494
607 + 31616887 = 31617494
787 + 31616707 = 31617494

Showing the first eight; more decompositions exist.
