Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492304, here are decompositions:

43 + 31492261 = 31492304
61 + 31492243 = 31492304
211 + 31492093 = 31492304
223 + 31492081 = 31492304
271 + 31492033 = 31492304
463 + 31491841 = 31492304
577 + 31491727 = 31492304
607 + 31491697 = 31492304

Showing the first eight; more decompositions exist.
