Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736, here are decompositions:

5 + 8731 = 8736
17 + 8719 = 8736
23 + 8713 = 8736
29 + 8707 = 8736
37 + 8699 = 8736
43 + 8693 = 8736
47 + 8689 = 8736
59 + 8677 = 8736

Showing the first eight; more decompositions exist.
