Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459722, here are decompositions:

5 + 31459717 = 31459722
13 + 31459709 = 31459722
43 + 31459679 = 31459722
61 + 31459661 = 31459722
71 + 31459651 = 31459722
89 + 31459633 = 31459722
101 + 31459621 = 31459722
103 + 31459619 = 31459722

Showing the first eight; more decompositions exist.
