Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476646, here are decompositions:

23 + 31476623 = 31476646
53 + 31476593 = 31476646
59 + 31476587 = 31476646
137 + 31476509 = 31476646
197 + 31476449 = 31476646
233 + 31476413 = 31476646
263 + 31476383 = 31476646
293 + 31476353 = 31476646

Showing the first eight; more decompositions exist.
