Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666382, here are decompositions:

13 + 8666369 = 8666382
31 + 8666351 = 8666382
59 + 8666323 = 8666382
113 + 8666269 = 8666382
163 + 8666219 = 8666382
181 + 8666201 = 8666382
199 + 8666183 = 8666382
223 + 8666159 = 8666382

Showing the first eight; more decompositions exist.
