Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486562, here are decompositions:

13 + 31486549 = 31486562
109 + 31486453 = 31486562
139 + 31486423 = 31486562
223 + 31486339 = 31486562
433 + 31486129 = 31486562
439 + 31486123 = 31486562
631 + 31485931 = 31486562
673 + 31485889 = 31486562

Showing the first eight; more decompositions exist.
