Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466992, here are decompositions:

3 + 31466989 = 31466992
23 + 31466969 = 31466992
41 + 31466951 = 31466992
59 + 31466933 = 31466992
233 + 31466759 = 31466992
239 + 31466753 = 31466992
443 + 31466549 = 31466992
701 + 31466291 = 31466992

Showing the first eight; more decompositions exist.
