Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459996, here are decompositions:

3 + 31459993 = 31459996
47 + 31459949 = 31459996
59 + 31459937 = 31459996
137 + 31459859 = 31459996
149 + 31459847 = 31459996
167 + 31459829 = 31459996
263 + 31459733 = 31459996
317 + 31459679 = 31459996

Showing the first eight; more decompositions exist.
