Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716578, here are decompositions:

11 + 8716567 = 8716578
47 + 8716531 = 8716578
89 + 8716489 = 8716578
109 + 8716469 = 8716578
127 + 8716451 = 8716578
131 + 8716447 = 8716578
137 + 8716441 = 8716578
139 + 8716439 = 8716578

Showing the first eight; more decompositions exist.
