Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668180, here are decompositions:

23 + 8668157 = 8668180
29 + 8668151 = 8668180
47 + 8668133 = 8668180
107 + 8668073 = 8668180
113 + 8668067 = 8668180
137 + 8668043 = 8668180
149 + 8668031 = 8668180
179 + 8668001 = 8668180

Showing the first eight; more decompositions exist.
