Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668158, here are decompositions:

7 + 8668151 = 8668158
17 + 8668141 = 8668158
47 + 8668111 = 8668158
97 + 8668061 = 8668158
101 + 8668057 = 8668158
127 + 8668031 = 8668158
157 + 8668001 = 8668158
179 + 8667979 = 8668158

Showing the first eight; more decompositions exist.
