Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667444, here are decompositions:

13 + 8667431 = 8667444
17 + 8667427 = 8667444
31 + 8667413 = 8667444
41 + 8667403 = 8667444
67 + 8667377 = 8667444
73 + 8667371 = 8667444
131 + 8667313 = 8667444
173 + 8667271 = 8667444

Showing the first eight; more decompositions exist.
