Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486566, here are decompositions:

17 + 31486549 = 31486566
29 + 31486537 = 31486566
37 + 31486529 = 31486566
73 + 31486493 = 31486566
103 + 31486463 = 31486566
109 + 31486457 = 31486566
113 + 31486453 = 31486566
149 + 31486417 = 31486566

Showing the first eight; more decompositions exist.
