Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672784, here are decompositions:

5 + 8672779 = 8672784
11 + 8672773 = 8672784
17 + 8672767 = 8672784
53 + 8672731 = 8672784
61 + 8672723 = 8672784
97 + 8672687 = 8672784
137 + 8672647 = 8672784
163 + 8672621 = 8672784

Showing the first eight; more decompositions exist.
