Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617698, here are decompositions:

19 + 31617679 = 31617698
31 + 31617667 = 31617698
67 + 31617631 = 31617698
139 + 31617559 = 31617698
241 + 31617457 = 31617698
337 + 31617361 = 31617698
499 + 31617199 = 31617698
769 + 31616929 = 31617698

Showing the first eight; more decompositions exist.
