Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459906, here are decompositions:

47 + 31459859 = 31459906
53 + 31459853 = 31459906
59 + 31459847 = 31459906
173 + 31459733 = 31459906
197 + 31459709 = 31459906
227 + 31459679 = 31459906
239 + 31459667 = 31459906
353 + 31459553 = 31459906

Showing the first eight; more decompositions exist.
