Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715648, here are decompositions:

31 + 8715617 = 8715648
47 + 8715601 = 8715648
59 + 8715589 = 8715648
61 + 8715587 = 8715648
89 + 8715559 = 8715648
197 + 8715451 = 8715648
199 + 8715449 = 8715648
239 + 8715409 = 8715648

Showing the first eight; more decompositions exist.
