Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702688, here are decompositions:

41 + 8702647 = 8702688
97 + 8702591 = 8702688
101 + 8702587 = 8702688
131 + 8702557 = 8702688
149 + 8702539 = 8702688
191 + 8702497 = 8702688
199 + 8702489 = 8702688
229 + 8702459 = 8702688

Showing the first eight; more decompositions exist.
