Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628784, here are decompositions:

5 + 8628779 = 8628784
11 + 8628773 = 8628784
107 + 8628677 = 8628784
137 + 8628647 = 8628784
233 + 8628551 = 8628784
401 + 8628383 = 8628784
431 + 8628353 = 8628784
491 + 8628293 = 8628784

Showing the first eight; more decompositions exist.
