Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459026, here are decompositions:

7 + 31459019 = 31459026
43 + 31458983 = 31459026
59 + 31458967 = 31459026
73 + 31458953 = 31459026
89 + 31458937 = 31459026
103 + 31458923 = 31459026
113 + 31458913 = 31459026
163 + 31458863 = 31459026

Showing the first eight; more decompositions exist.
