Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459876, here are decompositions:

17 + 31459859 = 31459876
23 + 31459853 = 31459876
29 + 31459847 = 31459876
47 + 31459829 = 31459876
167 + 31459709 = 31459876
179 + 31459697 = 31459876
197 + 31459679 = 31459876
257 + 31459619 = 31459876

Showing the first eight; more decompositions exist.
