Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466646, here are decompositions:

17 + 31466629 = 31466646
19 + 31466627 = 31466646
59 + 31466587 = 31466646
83 + 31466563 = 31466646
97 + 31466549 = 31466646
257 + 31466389 = 31466646
317 + 31466329 = 31466646
359 + 31466287 = 31466646

Showing the first eight; more decompositions exist.
