Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459494, here are decompositions:

7 + 31459487 = 31459494
37 + 31459457 = 31459494
61 + 31459433 = 31459494
107 + 31459387 = 31459494
137 + 31459357 = 31459494
151 + 31459343 = 31459494
173 + 31459321 = 31459494
233 + 31459261 = 31459494

Showing the first eight; more decompositions exist.
