Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459410, here are decompositions:

11 + 31459399 = 31459410
23 + 31459387 = 31459410
53 + 31459357 = 31459410
61 + 31459349 = 31459410
67 + 31459343 = 31459410
71 + 31459339 = 31459410
89 + 31459321 = 31459410
149 + 31459261 = 31459410

Showing the first eight; more decompositions exist.
