Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459070, here are decompositions:

7 + 31459063 = 31459070
103 + 31458967 = 31459070
157 + 31458913 = 31459070
163 + 31458907 = 31459070
241 + 31458829 = 31459070
271 + 31458799 = 31459070
283 + 31458787 = 31459070
367 + 31458703 = 31459070

Showing the first eight; more decompositions exist.
