Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660216, here are decompositions:

13 + 8660203 = 8660216
109 + 8660107 = 8660216
139 + 8660077 = 8660216
163 + 8660053 = 8660216
277 + 8659939 = 8660216
307 + 8659909 = 8660216
349 + 8659867 = 8660216
379 + 8659837 = 8660216

Showing the first eight; more decompositions exist.
