Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459794, here are decompositions:

61 + 31459733 = 31459794
71 + 31459723 = 31459794
97 + 31459697 = 31459794
127 + 31459667 = 31459794
173 + 31459621 = 31459794
241 + 31459553 = 31459794
277 + 31459517 = 31459794
307 + 31459487 = 31459794

Showing the first eight; more decompositions exist.
