Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666268, here are decompositions:

31 + 8666237 = 8666268
67 + 8666201 = 8666268
101 + 8666167 = 8666268
109 + 8666159 = 8666268
131 + 8666137 = 8666268
199 + 8666069 = 8666268
211 + 8666057 = 8666268
241 + 8666027 = 8666268

Showing the first eight; more decompositions exist.
