Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466866, here are decompositions:

17 + 31466849 = 31466866
107 + 31466759 = 31466866
113 + 31466753 = 31466866
173 + 31466693 = 31466866
239 + 31466627 = 31466866
269 + 31466597 = 31466866
317 + 31466549 = 31466866
479 + 31466387 = 31466866

Showing the first eight; more decompositions exist.
