Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464064, here are decompositions:

3 + 31464061 = 31464064
17 + 31464047 = 31464064
101 + 31463963 = 31464064
167 + 31463897 = 31464064
173 + 31463891 = 31464064
257 + 31463807 = 31464064
347 + 31463717 = 31464064
383 + 31463681 = 31464064

Showing the first eight; more decompositions exist.
