Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702784, here are decompositions:

7 + 8702777 = 8702784
31 + 8702753 = 8702784
37 + 8702747 = 8702784
53 + 8702731 = 8702784
137 + 8702647 = 8702784
191 + 8702593 = 8702784
193 + 8702591 = 8702784
197 + 8702587 = 8702784

Showing the first eight; more decompositions exist.
