Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459734, here are decompositions:

11 + 31459723 = 31459734
17 + 31459717 = 31459734
37 + 31459697 = 31459734
67 + 31459667 = 31459734
73 + 31459661 = 31459734
83 + 31459651 = 31459734
101 + 31459633 = 31459734
113 + 31459621 = 31459734

Showing the first eight; more decompositions exist.
