Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459628, here are decompositions:

7 + 31459621 = 31459628
19 + 31459609 = 31459628
229 + 31459399 = 31459628
241 + 31459387 = 31459628
271 + 31459357 = 31459628
307 + 31459321 = 31459628
337 + 31459291 = 31459628
367 + 31459261 = 31459628

Showing the first eight; more decompositions exist.
