Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668162, here are decompositions:

5 + 8668157 = 8668162
11 + 8668151 = 8668162
29 + 8668133 = 8668162
89 + 8668073 = 8668162
101 + 8668061 = 8668162
131 + 8668031 = 8668162
233 + 8667929 = 8668162
263 + 8667899 = 8668162

Showing the first eight; more decompositions exist.
