Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466776, here are decompositions:

17 + 31466759 = 31466776
23 + 31466753 = 31466776
83 + 31466693 = 31466776
149 + 31466627 = 31466776
179 + 31466597 = 31466776
227 + 31466549 = 31466776
389 + 31466387 = 31466776
449 + 31466327 = 31466776

Showing the first eight; more decompositions exist.
