Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617534, here are decompositions:

5 + 31617529 = 31617534
31 + 31617503 = 31617534
37 + 31617497 = 31617534
41 + 31617493 = 31617534
73 + 31617461 = 31617534
103 + 31617431 = 31617534
127 + 31617407 = 31617534
131 + 31617403 = 31617534

Showing the first eight; more decompositions exist.
