Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459416, here are decompositions:

7 + 31459409 = 31459416
17 + 31459399 = 31459416
29 + 31459387 = 31459416
59 + 31459357 = 31459416
67 + 31459349 = 31459416
73 + 31459343 = 31459416
127 + 31459289 = 31459416
193 + 31459223 = 31459416

Showing the first eight; more decompositions exist.
