Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459214, here are decompositions:

13 + 31459201 = 31459214
103 + 31459111 = 31459214
151 + 31459063 = 31459214
277 + 31458937 = 31459214
307 + 31458907 = 31459214
313 + 31458901 = 31459214
547 + 31458667 = 31459214
571 + 31458643 = 31459214

Showing the first eight; more decompositions exist.
