Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667328, here are decompositions:

29 + 8667299 = 8667328
71 + 8667257 = 8667328
101 + 8667227 = 8667328
149 + 8667179 = 8667328
191 + 8667137 = 8667328
389 + 8666939 = 8667328
401 + 8666927 = 8667328
479 + 8666849 = 8667328

Showing the first eight; more decompositions exist.
