Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668670, here are decompositions:

61 + 8668609 = 8668670
151 + 8668519 = 8668670
181 + 8668489 = 8668670
211 + 8668459 = 8668670
313 + 8668357 = 8668670
397 + 8668273 = 8668670
463 + 8668207 = 8668670
607 + 8668063 = 8668670

Showing the first eight; more decompositions exist.
