Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459010, here are decompositions:

43 + 31458967 = 31459010
73 + 31458937 = 31459010
97 + 31458913 = 31459010
103 + 31458907 = 31459010
109 + 31458901 = 31459010
181 + 31458829 = 31459010
211 + 31458799 = 31459010
223 + 31458787 = 31459010

Showing the first eight; more decompositions exist.
