Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459404, here are decompositions:

5 + 31459399 = 31459404
17 + 31459387 = 31459404
47 + 31459357 = 31459404
61 + 31459343 = 31459404
83 + 31459321 = 31459404
113 + 31459291 = 31459404
181 + 31459223 = 31459404
271 + 31459133 = 31459404

Showing the first eight; more decompositions exist.
