Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466580, here are decompositions:

17 + 31466563 = 31466580
31 + 31466549 = 31466580
179 + 31466401 = 31466580
191 + 31466389 = 31466580
193 + 31466387 = 31466580
199 + 31466381 = 31466580
239 + 31466341 = 31466580
251 + 31466329 = 31466580

Showing the first eight; more decompositions exist.
