Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667428, here are decompositions:

79 + 8667349 = 8667428
109 + 8667319 = 8667428
127 + 8667301 = 8667428
139 + 8667289 = 8667428
157 + 8667271 = 8667428
277 + 8667151 = 8667428
307 + 8667121 = 8667428
349 + 8667079 = 8667428

Showing the first eight; more decompositions exist.
