Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492922, here are decompositions:

73 + 31492849 = 31492922
151 + 31492771 = 31492922
271 + 31492651 = 31492922
499 + 31492423 = 31492922
523 + 31492399 = 31492922
661 + 31492261 = 31492922
709 + 31492213 = 31492922
829 + 31492093 = 31492922

Showing the first eight; more decompositions exist.
