Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466882, here are decompositions:

61 + 31466821 = 31466882
151 + 31466731 = 31466882
163 + 31466719 = 31466882
193 + 31466689 = 31466882
211 + 31466671 = 31466882
379 + 31466503 = 31466882
541 + 31466341 = 31466882
619 + 31466263 = 31466882

Showing the first eight; more decompositions exist.
