Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459608, here are decompositions:

67 + 31459541 = 31459608
109 + 31459499 = 31459608
151 + 31459457 = 31459608
199 + 31459409 = 31459608
251 + 31459357 = 31459608
269 + 31459339 = 31459608
317 + 31459291 = 31459608
347 + 31459261 = 31459608

Showing the first eight; more decompositions exist.
