Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686684, here are decompositions:

5 + 8686679 = 8686684
23 + 8686661 = 8686684
197 + 8686487 = 8686684
263 + 8686421 = 8686684
311 + 8686373 = 8686684
443 + 8686241 = 8686684
491 + 8686193 = 8686684
521 + 8686163 = 8686684

Showing the first eight; more decompositions exist.
