Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641696, here are decompositions:

23 + 8641673 = 8641696
53 + 8641643 = 8641696
83 + 8641613 = 8641696
149 + 8641547 = 8641696
179 + 8641517 = 8641696
227 + 8641469 = 8641696
263 + 8641433 = 8641696
347 + 8641349 = 8641696

Showing the first eight; more decompositions exist.
