Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667908, here are decompositions:

37 + 8667871 = 8667908
61 + 8667847 = 8667908
79 + 8667829 = 8667908
181 + 8667727 = 8667908
211 + 8667697 = 8667908
307 + 8667601 = 8667908
349 + 8667559 = 8667908
397 + 8667511 = 8667908

Showing the first eight; more decompositions exist.
