Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617694, here are decompositions:

5 + 31617689 = 31617694
107 + 31617587 = 31617694
131 + 31617563 = 31617694
191 + 31617503 = 31617694
197 + 31617497 = 31617694
233 + 31617461 = 31617694
263 + 31617431 = 31617694
281 + 31617413 = 31617694

Showing the first eight; more decompositions exist.
