Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667312, here are decompositions:

11 + 8667301 = 8667312
13 + 8667299 = 8667312
23 + 8667289 = 8667312
41 + 8667271 = 8667312
191 + 8667121 = 8667312
233 + 8667079 = 8667312
359 + 8666953 = 8667312
373 + 8666939 = 8667312

Showing the first eight; more decompositions exist.
