Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8651736, here are decompositions:

13 + 8651723 = 8651736
19 + 8651717 = 8651736
43 + 8651693 = 8651736
47 + 8651689 = 8651736
53 + 8651683 = 8651736
73 + 8651663 = 8651736
89 + 8651647 = 8651736
97 + 8651639 = 8651736

Showing the first eight; more decompositions exist.
