Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709666, here are decompositions:

13 + 8709653 = 8709666
19 + 8709647 = 8709666
79 + 8709587 = 8709666
103 + 8709563 = 8709666
113 + 8709553 = 8709666
139 + 8709527 = 8709666
157 + 8709509 = 8709666
197 + 8709469 = 8709666

Showing the first eight; more decompositions exist.
