Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459244, here are decompositions:

43 + 31459201 = 31459244
151 + 31459093 = 31459244
181 + 31459063 = 31459244
277 + 31458967 = 31459244
307 + 31458937 = 31459244
331 + 31458913 = 31459244
337 + 31458907 = 31459244
457 + 31458787 = 31459244

Showing the first eight; more decompositions exist.
