Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459094, here are decompositions:

31 + 31459063 = 31459094
127 + 31458967 = 31459094
157 + 31458937 = 31459094
181 + 31458913 = 31459094
193 + 31458901 = 31459094
307 + 31458787 = 31459094
397 + 31458697 = 31459094
463 + 31458631 = 31459094

Showing the first eight; more decompositions exist.
