Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667156, here are decompositions:

5 + 8667151 = 8667156
19 + 8667137 = 8667156
53 + 8667103 = 8667156
163 + 8666993 = 8667156
167 + 8666989 = 8667156
229 + 8666927 = 8667156
293 + 8666863 = 8667156
307 + 8666849 = 8667156

Showing the first eight; more decompositions exist.
