Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459846, here are decompositions:

17 + 31459829 = 31459846
113 + 31459733 = 31459846
137 + 31459709 = 31459846
149 + 31459697 = 31459846
167 + 31459679 = 31459846
179 + 31459667 = 31459846
227 + 31459619 = 31459846
293 + 31459553 = 31459846

Showing the first eight; more decompositions exist.
