Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459802, here are decompositions:

43 + 31459759 = 31459802
79 + 31459723 = 31459802
151 + 31459651 = 31459802
181 + 31459621 = 31459802
193 + 31459609 = 31459802
463 + 31459339 = 31459802
541 + 31459261 = 31459802
601 + 31459201 = 31459802

Showing the first eight; more decompositions exist.
