Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756784, here are decompositions:

13 + 8756771 = 8756784
97 + 8756687 = 8756784
107 + 8756677 = 8756784
131 + 8756653 = 8756784
151 + 8756633 = 8756784
191 + 8756593 = 8756784
193 + 8756591 = 8756784
227 + 8756557 = 8756784

Showing the first eight; more decompositions exist.
