Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668154, here are decompositions:

3 + 8668151 = 8668154
13 + 8668141 = 8668154
43 + 8668111 = 8668154
73 + 8668081 = 8668154
97 + 8668057 = 8668154
181 + 8667973 = 8668154
193 + 8667961 = 8668154
223 + 8667931 = 8668154

Showing the first eight; more decompositions exist.
