Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459508, here are decompositions:

109 + 31459399 = 31459508
151 + 31459357 = 31459508
307 + 31459201 = 31459508
397 + 31459111 = 31459508
439 + 31459069 = 31459508
541 + 31458967 = 31459508
571 + 31458937 = 31459508
601 + 31458907 = 31459508

Showing the first eight; more decompositions exist.
