Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727636, here are decompositions:

13 + 8727623 = 8727636
17 + 8727619 = 8727636
37 + 8727599 = 8727636
53 + 8727583 = 8727636
59 + 8727577 = 8727636
67 + 8727569 = 8727636
97 + 8727539 = 8727636
107 + 8727529 = 8727636

Showing the first eight; more decompositions exist.
