Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459020, here are decompositions:

37 + 31458983 = 31459020
53 + 31458967 = 31459020
67 + 31458953 = 31459020
83 + 31458937 = 31459020
97 + 31458923 = 31459020
107 + 31458913 = 31459020
113 + 31458907 = 31459020
157 + 31458863 = 31459020

Showing the first eight; more decompositions exist.
