Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550366, here are decompositions:

13 + 31550353 = 31550366
37 + 31550329 = 31550366
79 + 31550287 = 31550366
109 + 31550257 = 31550366
229 + 31550137 = 31550366
433 + 31549933 = 31550366
487 + 31549879 = 31550366
613 + 31549753 = 31550366

Showing the first eight; more decompositions exist.
