Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617612, here are decompositions:

29 + 31617583 = 31617612
53 + 31617559 = 31617612
79 + 31617533 = 31617612
83 + 31617529 = 31617612
109 + 31617503 = 31617612
151 + 31617461 = 31617612
163 + 31617449 = 31617612
181 + 31617431 = 31617612

Showing the first eight; more decompositions exist.
