Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660268, here are decompositions:

5 + 8660263 = 8660268
41 + 8660227 = 8660268
47 + 8660221 = 8660268
79 + 8660189 = 8660268
107 + 8660161 = 8660268
181 + 8660087 = 8660268
191 + 8660077 = 8660268
229 + 8660039 = 8660268

Showing the first eight; more decompositions exist.
