Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668258, here are decompositions:

101 + 8668157 = 8668258
107 + 8668151 = 8668258
191 + 8668067 = 8668258
197 + 8668061 = 8668258
227 + 8668031 = 8668258
257 + 8668001 = 8668258
359 + 8667899 = 8668258
449 + 8667809 = 8668258

Showing the first eight; more decompositions exist.
