Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668216, here are decompositions:

23 + 8668193 = 8668216
59 + 8668157 = 8668216
83 + 8668133 = 8668216
149 + 8668067 = 8668216
173 + 8668043 = 8668216
317 + 8667899 = 8668216
353 + 8667863 = 8668216
419 + 8667797 = 8668216

Showing the first eight; more decompositions exist.
