Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459066, here are decompositions:

3 + 31459063 = 31459066
47 + 31459019 = 31459066
83 + 31458983 = 31459066
113 + 31458953 = 31459066
269 + 31458797 = 31459066
347 + 31458719 = 31459066
479 + 31458587 = 31459066
647 + 31458419 = 31459066

Showing the first eight; more decompositions exist.
