Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609720, here are decompositions:

37 + 8609683 = 8609720
43 + 8609677 = 8609720
73 + 8609647 = 8609720
103 + 8609617 = 8609720
109 + 8609611 = 8609720
139 + 8609581 = 8609720
151 + 8609569 = 8609720
157 + 8609563 = 8609720

Showing the first eight; more decompositions exist.
