Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460048, here are decompositions:

31 + 31460017 = 31460048
157 + 31459891 = 31460048
199 + 31459849 = 31460048
241 + 31459807 = 31460048
331 + 31459717 = 31460048
397 + 31459651 = 31460048
439 + 31459609 = 31460048
661 + 31459387 = 31460048

Showing the first eight; more decompositions exist.
