Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459368, here are decompositions:

11 + 31459357 = 31459368
19 + 31459349 = 31459368
29 + 31459339 = 31459368
47 + 31459321 = 31459368
79 + 31459289 = 31459368
107 + 31459261 = 31459368
151 + 31459217 = 31459368
167 + 31459201 = 31459368

Showing the first eight; more decompositions exist.
