Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460146, here are decompositions:

17 + 31460129 = 31460146
83 + 31460063 = 31460146
197 + 31459949 = 31460146
293 + 31459853 = 31460146
317 + 31459829 = 31460146
449 + 31459697 = 31460146
467 + 31459679 = 31460146
479 + 31459667 = 31460146

Showing the first eight; more decompositions exist.
