Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667870, here are decompositions:

7 + 8667863 = 8667870
23 + 8667847 = 8667870
41 + 8667829 = 8667870
61 + 8667809 = 8667870
73 + 8667797 = 8667870
137 + 8667733 = 8667870
149 + 8667721 = 8667870
163 + 8667707 = 8667870

Showing the first eight; more decompositions exist.
