Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492924, here are decompositions:

3 + 31492921 = 31492924
17 + 31492907 = 31492924
83 + 31492841 = 31492924
167 + 31492757 = 31492924
173 + 31492751 = 31492924
227 + 31492697 = 31492924
233 + 31492691 = 31492924
257 + 31492667 = 31492924

Showing the first eight; more decompositions exist.
