Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653686, here are decompositions:

7 + 8653679 = 8653686
17 + 8653669 = 8653686
29 + 8653657 = 8653686
59 + 8653627 = 8653686
73 + 8653613 = 8653686
137 + 8653549 = 8653686
149 + 8653537 = 8653686
157 + 8653529 = 8653686

Showing the first eight; more decompositions exist.
