Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460222, here are decompositions:

223 + 31459999 = 31460222
229 + 31459993 = 31460222
331 + 31459891 = 31460222
373 + 31459849 = 31460222
463 + 31459759 = 31460222
499 + 31459723 = 31460222
571 + 31459651 = 31460222
601 + 31459621 = 31460222

Showing the first eight; more decompositions exist.
