Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459256, here are decompositions:

163 + 31459093 = 31459256
193 + 31459063 = 31459256
349 + 31458907 = 31459256
457 + 31458799 = 31459256
547 + 31458709 = 31459256
613 + 31458643 = 31459256
769 + 31458487 = 31459256
853 + 31458403 = 31459256

Showing the first eight; more decompositions exist.
