Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459832, here are decompositions:

3 + 31459829 = 31459832
73 + 31459759 = 31459832
109 + 31459723 = 31459832
181 + 31459651 = 31459832
199 + 31459633 = 31459832
211 + 31459621 = 31459832
223 + 31459609 = 31459832
433 + 31459399 = 31459832

Showing the first eight; more decompositions exist.
