Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459834, here are decompositions:

5 + 31459829 = 31459834
101 + 31459733 = 31459834
137 + 31459697 = 31459834
167 + 31459667 = 31459834
173 + 31459661 = 31459834
281 + 31459553 = 31459834
293 + 31459541 = 31459834
317 + 31459517 = 31459834

Showing the first eight; more decompositions exist.
