Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486592, here are decompositions:

43 + 31486549 = 31486592
139 + 31486453 = 31486592
199 + 31486393 = 31486592
463 + 31486129 = 31486592
619 + 31485973 = 31486592
661 + 31485931 = 31486592
769 + 31485823 = 31486592
1009 + 31485583 = 31486592

Showing the first eight; more decompositions exist.
