Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674872, here are decompositions:

5 + 8674867 = 8674872
13 + 8674859 = 8674872
53 + 8674819 = 8674872
79 + 8674793 = 8674872
103 + 8674769 = 8674872
113 + 8674759 = 8674872
179 + 8674693 = 8674872
191 + 8674681 = 8674872

Showing the first eight; more decompositions exist.
