Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660668, here are decompositions:

11 + 8660657 = 8660668
59 + 8660609 = 8660668
89 + 8660579 = 8660668
131 + 8660537 = 8660668
281 + 8660387 = 8660668
479 + 8660189 = 8660668
491 + 8660177 = 8660668
587 + 8660081 = 8660668

Showing the first eight; more decompositions exist.
