Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709660, here are decompositions:

7 + 8709653 = 8709660
13 + 8709647 = 8709660
73 + 8709587 = 8709660
97 + 8709563 = 8709660
107 + 8709553 = 8709660
151 + 8709509 = 8709660
191 + 8709469 = 8709660
199 + 8709461 = 8709660

Showing the first eight; more decompositions exist.
