Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674990, here are decompositions:

29 + 8674961 = 8674990
53 + 8674937 = 8674990
89 + 8674901 = 8674990
101 + 8674889 = 8674990
131 + 8674859 = 8674990
197 + 8674793 = 8674990
263 + 8674727 = 8674990
419 + 8674571 = 8674990

Showing the first eight; more decompositions exist.
