Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617654, here are decompositions:

23 + 31617631 = 31617654
67 + 31617587 = 31617654
71 + 31617583 = 31617654
151 + 31617503 = 31617654
157 + 31617497 = 31617654
193 + 31617461 = 31617654
197 + 31617457 = 31617654
223 + 31617431 = 31617654

Showing the first eight; more decompositions exist.
