Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459836, here are decompositions:

7 + 31459829 = 31459836
29 + 31459807 = 31459836
103 + 31459733 = 31459836
113 + 31459723 = 31459836
127 + 31459709 = 31459836
139 + 31459697 = 31459836
157 + 31459679 = 31459836
227 + 31459609 = 31459836

Showing the first eight; more decompositions exist.
