Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459764, here are decompositions:

5 + 31459759 = 31459764
31 + 31459733 = 31459764
41 + 31459723 = 31459764
47 + 31459717 = 31459764
67 + 31459697 = 31459764
97 + 31459667 = 31459764
103 + 31459661 = 31459764
113 + 31459651 = 31459764

Showing the first eight; more decompositions exist.
