Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459658, here are decompositions:

7 + 31459651 = 31459658
37 + 31459621 = 31459658
271 + 31459387 = 31459658
337 + 31459321 = 31459658
367 + 31459291 = 31459658
397 + 31459261 = 31459658
457 + 31459201 = 31459658
547 + 31459111 = 31459658

Showing the first eight; more decompositions exist.
