Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668236, here are decompositions:

29 + 8668207 = 8668236
43 + 8668193 = 8668236
79 + 8668157 = 8668236
103 + 8668133 = 8668236
163 + 8668073 = 8668236
173 + 8668063 = 8668236
179 + 8668057 = 8668236
193 + 8668043 = 8668236

Showing the first eight; more decompositions exist.
