Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667424, here are decompositions:

5 + 8667419 = 8667424
11 + 8667413 = 8667424
47 + 8667377 = 8667424
53 + 8667371 = 8667424
167 + 8667257 = 8667424
197 + 8667227 = 8667424
257 + 8667167 = 8667424
431 + 8666993 = 8667424

Showing the first eight; more decompositions exist.
