Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617566, here are decompositions:

3 + 31617563 = 31617566
7 + 31617559 = 31617566
37 + 31617529 = 31617566
73 + 31617493 = 31617566
109 + 31617457 = 31617566
157 + 31617409 = 31617566
163 + 31617403 = 31617566
193 + 31617373 = 31617566

Showing the first eight; more decompositions exist.
