Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736660, here are decompositions:

7 + 8736653 = 8736660
13 + 8736647 = 8736660
29 + 8736631 = 8736660
43 + 8736617 = 8736660
67 + 8736593 = 8736660
113 + 8736547 = 8736660
131 + 8736529 = 8736660
151 + 8736509 = 8736660

Showing the first eight; more decompositions exist.
