Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466756, here are decompositions:

3 + 31466753 = 31466756
7 + 31466749 = 31466756
37 + 31466719 = 31466756
43 + 31466713 = 31466756
67 + 31466689 = 31466756
127 + 31466629 = 31466756
193 + 31466563 = 31466756
367 + 31466389 = 31466756

Showing the first eight; more decompositions exist.
