Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459268, here are decompositions:

7 + 31459261 = 31459268
67 + 31459201 = 31459268
157 + 31459111 = 31459268
199 + 31459069 = 31459268
331 + 31458937 = 31459268
367 + 31458901 = 31459268
439 + 31458829 = 31459268
571 + 31458697 = 31459268

Showing the first eight; more decompositions exist.
