Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668886, here are decompositions:

13 + 8668873 = 8668886
73 + 8668813 = 8668886
103 + 8668783 = 8668886
199 + 8668687 = 8668886
277 + 8668609 = 8668886
337 + 8668549 = 8668886
367 + 8668519 = 8668886
397 + 8668489 = 8668886

Showing the first eight; more decompositions exist.
