Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666248, here are decompositions:

11 + 8666237 = 8666248
29 + 8666219 = 8666248
47 + 8666201 = 8666248
89 + 8666159 = 8666248
179 + 8666069 = 8666248
191 + 8666057 = 8666248
197 + 8666051 = 8666248
257 + 8665991 = 8666248

Showing the first eight; more decompositions exist.
