Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459848, here are decompositions:

19 + 31459829 = 31459848
41 + 31459807 = 31459848
89 + 31459759 = 31459848
131 + 31459717 = 31459848
139 + 31459709 = 31459848
151 + 31459697 = 31459848
181 + 31459667 = 31459848
197 + 31459651 = 31459848

Showing the first eight; more decompositions exist.
