Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460494, here are decompositions:

3 + 31460491 = 31460494
11 + 31460483 = 31460494
53 + 31460441 = 31460494
173 + 31460321 = 31460494
227 + 31460267 = 31460494
431 + 31460063 = 31460494
557 + 31459937 = 31460494
563 + 31459931 = 31460494

Showing the first eight; more decompositions exist.
