Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459446, here are decompositions:

13 + 31459433 = 31459446
37 + 31459409 = 31459446
47 + 31459399 = 31459446
59 + 31459387 = 31459446
89 + 31459357 = 31459446
97 + 31459349 = 31459446
103 + 31459343 = 31459446
107 + 31459339 = 31459446

Showing the first eight; more decompositions exist.
