Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667240, here are decompositions:

13 + 8667227 = 8667240
61 + 8667179 = 8667240
73 + 8667167 = 8667240
89 + 8667151 = 8667240
103 + 8667137 = 8667240
137 + 8667103 = 8667240
251 + 8666989 = 8667240
313 + 8666927 = 8667240

Showing the first eight; more decompositions exist.
