Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459160, here are decompositions:

37 + 31459123 = 31459160
67 + 31459093 = 31459160
97 + 31459063 = 31459160
193 + 31458967 = 31459160
223 + 31458937 = 31459160
331 + 31458829 = 31459160
373 + 31458787 = 31459160
457 + 31458703 = 31459160

Showing the first eight; more decompositions exist.
