Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459050, here are decompositions:

19 + 31459031 = 31459050
31 + 31459019 = 31459050
67 + 31458983 = 31459050
83 + 31458967 = 31459050
97 + 31458953 = 31459050
113 + 31458937 = 31459050
127 + 31458923 = 31459050
137 + 31458913 = 31459050

Showing the first eight; more decompositions exist.
