Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667784, here are decompositions:

107 + 8667677 = 8667784
131 + 8667653 = 8667784
173 + 8667611 = 8667784
263 + 8667521 = 8667784
353 + 8667431 = 8667784
557 + 8667227 = 8667784
617 + 8667167 = 8667784
647 + 8667137 = 8667784

Showing the first eight; more decompositions exist.
