Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668330, here are decompositions:

29 + 8668301 = 8668330
137 + 8668193 = 8668330
173 + 8668157 = 8668330
179 + 8668151 = 8668330
197 + 8668133 = 8668330
257 + 8668073 = 8668330
263 + 8668067 = 8668330
269 + 8668061 = 8668330

Showing the first eight; more decompositions exist.
