Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459102, here are decompositions:

29 + 31459073 = 31459102
71 + 31459031 = 31459102
83 + 31459019 = 31459102
149 + 31458953 = 31459102
179 + 31458923 = 31459102
239 + 31458863 = 31459102
281 + 31458821 = 31459102
383 + 31458719 = 31459102

Showing the first eight; more decompositions exist.
