Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460068, here are decompositions:

5 + 31460063 = 31460068
131 + 31459937 = 31460068
137 + 31459931 = 31460068
239 + 31459829 = 31460068
359 + 31459709 = 31460068
389 + 31459679 = 31460068
401 + 31459667 = 31460068
449 + 31459619 = 31460068

Showing the first eight; more decompositions exist.
