Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459874, here are decompositions:

67 + 31459807 = 31459874
151 + 31459723 = 31459874
157 + 31459717 = 31459874
223 + 31459651 = 31459874
241 + 31459633 = 31459874
487 + 31459387 = 31459874
613 + 31459261 = 31459874
673 + 31459201 = 31459874

Showing the first eight; more decompositions exist.
