Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617644, here are decompositions:

13 + 31617631 = 31617644
61 + 31617583 = 31617644
151 + 31617493 = 31617644
241 + 31617403 = 31617644
271 + 31617373 = 31617644
283 + 31617361 = 31617644
463 + 31617181 = 31617644
571 + 31617073 = 31617644

Showing the first eight; more decompositions exist.
