Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466588, here are decompositions:

199 + 31466389 = 31466588
331 + 31466257 = 31466588
337 + 31466251 = 31466588
367 + 31466221 = 31466588
487 + 31466101 = 31466588
499 + 31466089 = 31466588
709 + 31465879 = 31466588
739 + 31465849 = 31466588

Showing the first eight; more decompositions exist.
