Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668210, here are decompositions:

3 + 8668207 = 8668210
17 + 8668193 = 8668210
53 + 8668157 = 8668210
59 + 8668151 = 8668210
137 + 8668073 = 8668210
149 + 8668061 = 8668210
167 + 8668043 = 8668210
179 + 8668031 = 8668210

Showing the first eight; more decompositions exist.
