Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459826, here are decompositions:

19 + 31459807 = 31459826
67 + 31459759 = 31459826
103 + 31459723 = 31459826
109 + 31459717 = 31459826
193 + 31459633 = 31459826
439 + 31459387 = 31459826
487 + 31459339 = 31459826
733 + 31459093 = 31459826

Showing the first eight; more decompositions exist.
