Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617652, here are decompositions:

23 + 31617629 = 31617652
89 + 31617563 = 31617652
149 + 31617503 = 31617652
191 + 31617461 = 31617652
239 + 31617413 = 31617652
281 + 31617371 = 31617652
359 + 31617293 = 31617652
383 + 31617269 = 31617652

Showing the first eight; more decompositions exist.
