Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460002, here are decompositions:

3 + 31459999 = 31460002
53 + 31459949 = 31460002
71 + 31459931 = 31460002
149 + 31459853 = 31460002
173 + 31459829 = 31460002
269 + 31459733 = 31460002
293 + 31459709 = 31460002
383 + 31459619 = 31460002

Showing the first eight; more decompositions exist.
