Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459926, here are decompositions:

67 + 31459859 = 31459926
73 + 31459853 = 31459926
79 + 31459847 = 31459926
97 + 31459829 = 31459926
167 + 31459759 = 31459926
193 + 31459733 = 31459926
229 + 31459697 = 31459926
293 + 31459633 = 31459926

Showing the first eight; more decompositions exist.
