Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459910, here are decompositions:

19 + 31459891 = 31459910
61 + 31459849 = 31459910
103 + 31459807 = 31459910
151 + 31459759 = 31459910
193 + 31459717 = 31459910
277 + 31459633 = 31459910
523 + 31459387 = 31459910
571 + 31459339 = 31459910

Showing the first eight; more decompositions exist.
