Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667340, here are decompositions:

41 + 8667299 = 8667340
83 + 8667257 = 8667340
113 + 8667227 = 8667340
173 + 8667167 = 8667340
347 + 8666993 = 8667340
401 + 8666939 = 8667340
449 + 8666891 = 8667340
491 + 8666849 = 8667340

Showing the first eight; more decompositions exist.
