Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609620, here are decompositions:

3 + 8609617 = 8609620
11 + 8609609 = 8609620
23 + 8609597 = 8609620
29 + 8609591 = 8609620
137 + 8609483 = 8609620
179 + 8609441 = 8609620
311 + 8609309 = 8609620
347 + 8609273 = 8609620

Showing the first eight; more decompositions exist.
