Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466620, here are decompositions:

23 + 31466597 = 31466620
71 + 31466549 = 31466620
233 + 31466387 = 31466620
239 + 31466381 = 31466620
293 + 31466327 = 31466620
557 + 31466063 = 31466620
569 + 31466051 = 31466620
617 + 31466003 = 31466620

Showing the first eight; more decompositions exist.
