Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466814, here are decompositions:

23 + 31466791 = 31466814
61 + 31466753 = 31466814
83 + 31466731 = 31466814
101 + 31466713 = 31466814
107 + 31466707 = 31466814
157 + 31466657 = 31466814
227 + 31466587 = 31466814
251 + 31466563 = 31466814

Showing the first eight; more decompositions exist.
