Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668278, here are decompositions:

5 + 8668273 = 8668278
11 + 8668267 = 8668278
71 + 8668207 = 8668278
127 + 8668151 = 8668278
137 + 8668141 = 8668278
167 + 8668111 = 8668278
197 + 8668081 = 8668278
211 + 8668067 = 8668278

Showing the first eight; more decompositions exist.
