Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466586, here are decompositions:

23 + 31466563 = 31466586
37 + 31466549 = 31466586
83 + 31466503 = 31466586
197 + 31466389 = 31466586
199 + 31466387 = 31466586
257 + 31466329 = 31466586
337 + 31466249 = 31466586
353 + 31466233 = 31466586

Showing the first eight; more decompositions exist.
