Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617630, here are decompositions:

43 + 31617587 = 31617630
47 + 31617583 = 31617630
67 + 31617563 = 31617630
71 + 31617559 = 31617630
97 + 31617533 = 31617630
101 + 31617529 = 31617630
127 + 31617503 = 31617630
137 + 31617493 = 31617630

Showing the first eight; more decompositions exist.
