Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630784, here are decompositions:

5 + 8630779 = 8630784
13 + 8630771 = 8630784
47 + 8630737 = 8630784
101 + 8630683 = 8630784
131 + 8630653 = 8630784
137 + 8630647 = 8630784
191 + 8630593 = 8630784
193 + 8630591 = 8630784

Showing the first eight; more decompositions exist.
