Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459864, here are decompositions:

5 + 31459859 = 31459864
11 + 31459853 = 31459864
17 + 31459847 = 31459864
131 + 31459733 = 31459864
167 + 31459697 = 31459864
197 + 31459667 = 31459864
311 + 31459553 = 31459864
347 + 31459517 = 31459864

Showing the first eight; more decompositions exist.
