Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667078, here are decompositions:

89 + 8666989 = 8667078
139 + 8666939 = 8667078
151 + 8666927 = 8667078
197 + 8666881 = 8667078
229 + 8666849 = 8667078
239 + 8666839 = 8667078
269 + 8666809 = 8667078
271 + 8666807 = 8667078

Showing the first eight; more decompositions exist.
