Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617862, here are decompositions:

149 + 31617713 = 31617862
173 + 31617689 = 31617862
233 + 31617629 = 31617862
359 + 31617503 = 31617862
401 + 31617461 = 31617862
431 + 31617431 = 31617862
449 + 31617413 = 31617862
491 + 31617371 = 31617862

Showing the first eight; more decompositions exist.
