Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459724, here are decompositions:

7 + 31459717 = 31459724
73 + 31459651 = 31459724
103 + 31459621 = 31459724
337 + 31459387 = 31459724
367 + 31459357 = 31459724
433 + 31459291 = 31459724
463 + 31459261 = 31459724
523 + 31459201 = 31459724

Showing the first eight; more decompositions exist.
