Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668146, here are decompositions:

5 + 8668141 = 8668146
13 + 8668133 = 8668146
73 + 8668073 = 8668146
79 + 8668067 = 8668146
83 + 8668063 = 8668146
89 + 8668057 = 8668146
103 + 8668043 = 8668146
167 + 8667979 = 8668146

Showing the first eight; more decompositions exist.
