Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726784, here are decompositions:

7 + 8726777 = 8726784
23 + 8726761 = 8726784
47 + 8726737 = 8726784
61 + 8726723 = 8726784
71 + 8726713 = 8726784
97 + 8726687 = 8726784
107 + 8726677 = 8726784
113 + 8726671 = 8726784

Showing the first eight; more decompositions exist.
