Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666802, here are decompositions:

5 + 8666797 = 8666802
19 + 8666783 = 8666802
29 + 8666773 = 8666802
211 + 8666591 = 8666802
269 + 8666533 = 8666802
283 + 8666519 = 8666802
311 + 8666491 = 8666802
359 + 8666443 = 8666802

Showing the first eight; more decompositions exist.
