Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667430, here are decompositions:

3 + 8667427 = 8667430
11 + 8667419 = 8667430
17 + 8667413 = 8667430
53 + 8667377 = 8667430
59 + 8667371 = 8667430
131 + 8667299 = 8667430
173 + 8667257 = 8667430
251 + 8667179 = 8667430

Showing the first eight; more decompositions exist.
