Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466566, here are decompositions:

3 + 31466563 = 31466566
17 + 31466549 = 31466566
179 + 31466387 = 31466566
239 + 31466327 = 31466566
317 + 31466249 = 31466566
359 + 31466207 = 31466566
503 + 31466063 = 31466566
563 + 31466003 = 31466566

Showing the first eight; more decompositions exist.
