Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459884, here are decompositions:

31 + 31459853 = 31459884
37 + 31459847 = 31459884
151 + 31459733 = 31459884
167 + 31459717 = 31459884
223 + 31459661 = 31459884
233 + 31459651 = 31459884
251 + 31459633 = 31459884
263 + 31459621 = 31459884

Showing the first eight; more decompositions exist.
