Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459166, here are decompositions:

43 + 31459123 = 31459166
73 + 31459093 = 31459166
97 + 31459069 = 31459166
103 + 31459063 = 31459166
199 + 31458967 = 31459166
229 + 31458937 = 31459166
337 + 31458829 = 31459166
367 + 31458799 = 31459166

Showing the first eight; more decompositions exist.
