Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706644, here are decompositions:

31 + 8706613 = 8706644
97 + 8706547 = 8706644
181 + 8706463 = 8706644
241 + 8706403 = 8706644
277 + 8706367 = 8706644
283 + 8706361 = 8706644
307 + 8706337 = 8706644
367 + 8706277 = 8706644

Showing the first eight; more decompositions exist.
