Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459726, here are decompositions:

3 + 31459723 = 31459726
17 + 31459709 = 31459726
29 + 31459697 = 31459726
47 + 31459679 = 31459726
59 + 31459667 = 31459726
107 + 31459619 = 31459726
173 + 31459553 = 31459726
227 + 31459499 = 31459726

Showing the first eight; more decompositions exist.
