Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668288, here are decompositions:

131 + 8668157 = 8668288
137 + 8668151 = 8668288
227 + 8668061 = 8668288
257 + 8668031 = 8668288
359 + 8667929 = 8668288
389 + 8667899 = 8668288
467 + 8667821 = 8668288
479 + 8667809 = 8668288

Showing the first eight; more decompositions exist.
