Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736666, here are decompositions:

7 + 8736659 = 8736666
13 + 8736653 = 8736666
19 + 8736647 = 8736666
73 + 8736593 = 8736666
83 + 8736583 = 8736666
137 + 8736529 = 8736666
157 + 8736509 = 8736666
163 + 8736503 = 8736666

Showing the first eight; more decompositions exist.
