Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459566, here are decompositions:

13 + 31459553 = 31459566
67 + 31459499 = 31459566
79 + 31459487 = 31459566
109 + 31459457 = 31459566
157 + 31459409 = 31459566
167 + 31459399 = 31459566
179 + 31459387 = 31459566
223 + 31459343 = 31459566

Showing the first eight; more decompositions exist.
