Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660340, here are decompositions:

43 + 8660297 = 8660340
53 + 8660287 = 8660340
71 + 8660269 = 8660340
107 + 8660233 = 8660340
113 + 8660227 = 8660340
137 + 8660203 = 8660340
151 + 8660189 = 8660340
163 + 8660177 = 8660340

Showing the first eight; more decompositions exist.
