Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686672, here are decompositions:

3 + 8686669 = 8686672
11 + 8686661 = 8686672
83 + 8686589 = 8686672
173 + 8686499 = 8686672
251 + 8686421 = 8686672
263 + 8686409 = 8686672
311 + 8686361 = 8686672
359 + 8686313 = 8686672

Showing the first eight; more decompositions exist.
