Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667418, here are decompositions:

5 + 8667413 = 8667418
41 + 8667377 = 8667418
47 + 8667371 = 8667418
191 + 8667227 = 8667418
239 + 8667179 = 8667418
251 + 8667167 = 8667418
281 + 8667137 = 8667418
479 + 8666939 = 8667418

Showing the first eight; more decompositions exist.
