Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459716, here are decompositions:

7 + 31459709 = 31459716
19 + 31459697 = 31459716
37 + 31459679 = 31459716
83 + 31459633 = 31459716
97 + 31459619 = 31459716
107 + 31459609 = 31459716
163 + 31459553 = 31459716
199 + 31459517 = 31459716

Showing the first eight; more decompositions exist.
