Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459008, here are decompositions:

41 + 31458967 = 31459008
71 + 31458937 = 31459008
101 + 31458907 = 31459008
107 + 31458901 = 31459008
179 + 31458829 = 31459008
211 + 31458797 = 31459008
307 + 31458701 = 31459008
311 + 31458697 = 31459008

Showing the first eight; more decompositions exist.
