Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486634, here are decompositions:

7 + 31486627 = 31486634
31 + 31486603 = 31486634
97 + 31486537 = 31486634
181 + 31486453 = 31486634
211 + 31486423 = 31486634
241 + 31486393 = 31486634
307 + 31486327 = 31486634
331 + 31486303 = 31486634

Showing the first eight; more decompositions exist.
