Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637686, here are decompositions:

19 + 8637667 = 8637686
67 + 8637619 = 8637686
163 + 8637523 = 8637686
193 + 8637493 = 8637686
307 + 8637379 = 8637686
313 + 8637373 = 8637686
349 + 8637337 = 8637686
367 + 8637319 = 8637686

Showing the first eight; more decompositions exist.
