Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660918, here are decompositions:

31 + 8660887 = 8660918
151 + 8660767 = 8660918
229 + 8660689 = 8660918
307 + 8660611 = 8660918
349 + 8660569 = 8660918
379 + 8660539 = 8660918
457 + 8660461 = 8660918
499 + 8660419 = 8660918

Showing the first eight; more decompositions exist.
