Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459266, here are decompositions:

5 + 31459261 = 31459266
43 + 31459223 = 31459266
67 + 31459199 = 31459266
173 + 31459093 = 31459266
193 + 31459073 = 31459266
197 + 31459069 = 31459266
283 + 31458983 = 31459266
313 + 31458953 = 31459266

Showing the first eight; more decompositions exist.
