Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668272, here are decompositions:

5 + 8668267 = 8668272
71 + 8668201 = 8668272
79 + 8668193 = 8668272
131 + 8668141 = 8668272
139 + 8668133 = 8668272
191 + 8668081 = 8668272
199 + 8668073 = 8668272
211 + 8668061 = 8668272

Showing the first eight; more decompositions exist.
