Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466964, here are decompositions:

13 + 31466951 = 31466964
31 + 31466933 = 31466964
71 + 31466893 = 31466964
97 + 31466867 = 31466964
107 + 31466857 = 31466964
173 + 31466791 = 31466964
211 + 31466753 = 31466964
233 + 31466731 = 31466964

Showing the first eight; more decompositions exist.
