Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674890, here are decompositions:

23 + 8674867 = 8674890
31 + 8674859 = 8674890
71 + 8674819 = 8674890
97 + 8674793 = 8674890
109 + 8674781 = 8674890
131 + 8674759 = 8674890
163 + 8674727 = 8674890
197 + 8674693 = 8674890

Showing the first eight; more decompositions exist.
