Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668688, here are decompositions:

79 + 8668609 = 8668688
139 + 8668549 = 8668688
199 + 8668489 = 8668688
229 + 8668459 = 8668688
307 + 8668381 = 8668688
331 + 8668357 = 8668688
409 + 8668279 = 8668688
421 + 8668267 = 8668688

Showing the first eight; more decompositions exist.
