Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667900, here are decompositions:

29 + 8667871 = 8667900
37 + 8667863 = 8667900
53 + 8667847 = 8667900
71 + 8667829 = 8667900
79 + 8667821 = 8667900
103 + 8667797 = 8667900
107 + 8667793 = 8667900
167 + 8667733 = 8667900

Showing the first eight; more decompositions exist.
