Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709720, here are decompositions:

7 + 8709713 = 8709720
23 + 8709697 = 8709720
43 + 8709677 = 8709720
67 + 8709653 = 8709720
73 + 8709647 = 8709720
109 + 8709611 = 8709720
157 + 8709563 = 8709720
167 + 8709553 = 8709720

Showing the first eight; more decompositions exist.
