Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459822, here are decompositions:

89 + 31459733 = 31459822
113 + 31459709 = 31459822
269 + 31459553 = 31459822
281 + 31459541 = 31459822
389 + 31459433 = 31459822
479 + 31459343 = 31459822
599 + 31459223 = 31459822
839 + 31458983 = 31459822

Showing the first eight; more decompositions exist.
