Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660558, here are decompositions:

19 + 8660539 = 8660558
31 + 8660527 = 8660558
97 + 8660461 = 8660558
139 + 8660419 = 8660558
157 + 8660401 = 8660558
271 + 8660287 = 8660558
331 + 8660227 = 8660558
337 + 8660221 = 8660558

Showing the first eight; more decompositions exist.
