Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667144, here are decompositions:

7 + 8667137 = 8667144
23 + 8667121 = 8667144
41 + 8667103 = 8667144
151 + 8666993 = 8667144
191 + 8666953 = 8667144
263 + 8666881 = 8667144
281 + 8666863 = 8667144
337 + 8666807 = 8667144

Showing the first eight; more decompositions exist.
