Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689616, here are decompositions:

7 + 8689609 = 8689616
43 + 8689573 = 8689616
73 + 8689543 = 8689616
79 + 8689537 = 8689616
127 + 8689489 = 8689616
163 + 8689453 = 8689616
307 + 8689309 = 8689616
337 + 8689279 = 8689616

Showing the first eight; more decompositions exist.
