Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667442, here are decompositions:

11 + 8667431 = 8667442
23 + 8667419 = 8667442
29 + 8667413 = 8667442
71 + 8667371 = 8667442
263 + 8667179 = 8667442
449 + 8666993 = 8667442
503 + 8666939 = 8667442
593 + 8666849 = 8667442

Showing the first eight; more decompositions exist.
