Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459016, here are decompositions:

79 + 31458937 = 31459016
103 + 31458913 = 31459016
109 + 31458907 = 31459016
229 + 31458787 = 31459016
307 + 31458709 = 31459016
313 + 31458703 = 31459016
349 + 31458667 = 31459016
373 + 31458643 = 31459016

Showing the first eight; more decompositions exist.
