Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667072, here are decompositions:

79 + 8666993 = 8667072
83 + 8666989 = 8667072
181 + 8666891 = 8667072
191 + 8666881 = 8667072
223 + 8666849 = 8667072
233 + 8666839 = 8667072
263 + 8666809 = 8667072
389 + 8666683 = 8667072

Showing the first eight; more decompositions exist.
