Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668438, here are decompositions:

17 + 8668421 = 8668438
59 + 8668379 = 8668438
71 + 8668367 = 8668438
89 + 8668349 = 8668438
137 + 8668301 = 8668438
281 + 8668157 = 8668438
509 + 8667929 = 8668438
617 + 8667821 = 8668438

Showing the first eight; more decompositions exist.
