Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674728, here are decompositions:

47 + 8674681 = 8674728
61 + 8674667 = 8674728
109 + 8674619 = 8674728
151 + 8674577 = 8674728
157 + 8674571 = 8674728
191 + 8674537 = 8674728
197 + 8674531 = 8674728
229 + 8674499 = 8674728

Showing the first eight; more decompositions exist.
