Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660786, here are decompositions:

19 + 8660767 = 8660786
97 + 8660689 = 8660786
103 + 8660683 = 8660786
163 + 8660623 = 8660786
283 + 8660503 = 8660786
349 + 8660437 = 8660786
367 + 8660419 = 8660786
373 + 8660413 = 8660786

Showing the first eight; more decompositions exist.
