Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459116, here are decompositions:

5 + 31459111 = 31459116
23 + 31459093 = 31459116
43 + 31459073 = 31459116
47 + 31459069 = 31459116
53 + 31459063 = 31459116
97 + 31459019 = 31459116
149 + 31458967 = 31459116
163 + 31458953 = 31459116

Showing the first eight; more decompositions exist.
