Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668156, here are decompositions:

5 + 8668151 = 8668156
23 + 8668133 = 8668156
83 + 8668073 = 8668156
89 + 8668067 = 8668156
113 + 8668043 = 8668156
227 + 8667929 = 8668156
257 + 8667899 = 8668156
293 + 8667863 = 8668156

Showing the first eight; more decompositions exist.
