Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8698784, here are decompositions:

7 + 8698777 = 8698784
103 + 8698681 = 8698784
151 + 8698633 = 8698784
163 + 8698621 = 8698784
181 + 8698603 = 8698784
421 + 8698363 = 8698784
487 + 8698297 = 8698784
571 + 8698213 = 8698784

Showing the first eight; more decompositions exist.
