Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668380, here are decompositions:

11 + 8668369 = 8668380
13 + 8668367 = 8668380
23 + 8668357 = 8668380
31 + 8668349 = 8668380
79 + 8668301 = 8668380
101 + 8668279 = 8668380
107 + 8668273 = 8668380
113 + 8668267 = 8668380

Showing the first eight; more decompositions exist.
