Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736644, here are decompositions:

13 + 8736631 = 8736644
61 + 8736583 = 8736644
97 + 8736547 = 8736644
181 + 8736463 = 8736644
211 + 8736433 = 8736644
277 + 8736367 = 8736644
421 + 8736223 = 8736644
457 + 8736187 = 8736644

Showing the first eight; more decompositions exist.
