Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674638, here are decompositions:

19 + 8674619 = 8674638
61 + 8674577 = 8674638
67 + 8674571 = 8674638
101 + 8674537 = 8674638
107 + 8674531 = 8674638
127 + 8674511 = 8674638
139 + 8674499 = 8674638
149 + 8674489 = 8674638

Showing the first eight; more decompositions exist.
