Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715784, here are decompositions:

5 + 8715779 = 8715784
23 + 8715761 = 8715784
53 + 8715731 = 8715784
113 + 8715671 = 8715784
131 + 8715653 = 8715784
137 + 8715647 = 8715784
167 + 8715617 = 8715784
197 + 8715587 = 8715784

Showing the first eight; more decompositions exist.
