Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459068, here are decompositions:

5 + 31459063 = 31459068
37 + 31459031 = 31459068
101 + 31458967 = 31459068
131 + 31458937 = 31459068
167 + 31458901 = 31459068
239 + 31458829 = 31459068
269 + 31458799 = 31459068
271 + 31458797 = 31459068

Showing the first eight; more decompositions exist.
