Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8784, here are decompositions:

5 + 8779 = 8784
23 + 8761 = 8784
31 + 8753 = 8784
37 + 8747 = 8784
43 + 8741 = 8784
47 + 8737 = 8784
53 + 8731 = 8784
71 + 8713 = 8784

Showing the first eight; more decompositions exist.
