Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459892, here are decompositions:

43 + 31459849 = 31459892
241 + 31459651 = 31459892
271 + 31459621 = 31459892
283 + 31459609 = 31459892
571 + 31459321 = 31459892
601 + 31459291 = 31459892
631 + 31459261 = 31459892
691 + 31459201 = 31459892

Showing the first eight; more decompositions exist.
