Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668284, here are decompositions:

5 + 8668279 = 8668284
11 + 8668273 = 8668284
17 + 8668267 = 8668284
83 + 8668201 = 8668284
127 + 8668157 = 8668284
151 + 8668133 = 8668284
173 + 8668111 = 8668284
211 + 8668073 = 8668284

Showing the first eight; more decompositions exist.
