Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667490, here are decompositions:

59 + 8667431 = 8667490
71 + 8667419 = 8667490
113 + 8667377 = 8667490
191 + 8667299 = 8667490
233 + 8667257 = 8667490
263 + 8667227 = 8667490
311 + 8667179 = 8667490
353 + 8667137 = 8667490

Showing the first eight; more decompositions exist.
