Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660438, here are decompositions:

19 + 8660419 = 8660438
37 + 8660401 = 8660438
151 + 8660287 = 8660438
211 + 8660227 = 8660438
277 + 8660161 = 8660438
331 + 8660107 = 8660438
439 + 8659999 = 8660438
499 + 8659939 = 8660438

Showing the first eight; more decompositions exist.
