Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688836, here are decompositions:

7 + 8688829 = 8688836
19 + 8688817 = 8688836
97 + 8688739 = 8688836
139 + 8688697 = 8688836
223 + 8688613 = 8688836
229 + 8688607 = 8688836
283 + 8688553 = 8688836
367 + 8688469 = 8688836

Showing the first eight; more decompositions exist.
