Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632620, here are decompositions:

11 + 8632609 = 8632620
23 + 8632597 = 8632620
41 + 8632579 = 8632620
47 + 8632573 = 8632620
89 + 8632531 = 8632620
97 + 8632523 = 8632620
107 + 8632513 = 8632620
127 + 8632493 = 8632620

Showing the first eight; more decompositions exist.
