Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636586, here are decompositions:

5 + 8636581 = 8636586
37 + 8636549 = 8636586
43 + 8636543 = 8636586
47 + 8636539 = 8636586
53 + 8636533 = 8636586
73 + 8636513 = 8636586
113 + 8636473 = 8636586
137 + 8636449 = 8636586

Showing the first eight; more decompositions exist.
