Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668230, here are decompositions:

23 + 8668207 = 8668230
29 + 8668201 = 8668230
37 + 8668193 = 8668230
73 + 8668157 = 8668230
79 + 8668151 = 8668230
89 + 8668141 = 8668230
97 + 8668133 = 8668230
149 + 8668081 = 8668230

Showing the first eight; more decompositions exist.
