Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459080, here are decompositions:

7 + 31459073 = 31459080
11 + 31459069 = 31459080
17 + 31459063 = 31459080
61 + 31459019 = 31459080
97 + 31458983 = 31459080
113 + 31458967 = 31459080
127 + 31458953 = 31459080
157 + 31458923 = 31459080

Showing the first eight; more decompositions exist.
