Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617582, here are decompositions:

19 + 31617563 = 31617582
23 + 31617559 = 31617582
53 + 31617529 = 31617582
79 + 31617503 = 31617582
89 + 31617493 = 31617582
151 + 31617431 = 31617582
173 + 31617409 = 31617582
179 + 31617403 = 31617582

Showing the first eight; more decompositions exist.
