Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459106, here are decompositions:

13 + 31459093 = 31459106
37 + 31459069 = 31459106
43 + 31459063 = 31459106
139 + 31458967 = 31459106
193 + 31458913 = 31459106
199 + 31458907 = 31459106
277 + 31458829 = 31459106
307 + 31458799 = 31459106

Showing the first eight; more decompositions exist.
