Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459616, here are decompositions:

7 + 31459609 = 31459616
229 + 31459387 = 31459616
277 + 31459339 = 31459616
523 + 31459093 = 31459616
547 + 31459069 = 31459616
709 + 31458907 = 31459616
787 + 31458829 = 31459616
829 + 31458787 = 31459616

Showing the first eight; more decompositions exist.
