Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641516, here are decompositions:

3 + 8641513 = 8641516
47 + 8641469 = 8641516
83 + 8641433 = 8641516
167 + 8641349 = 8641516
197 + 8641319 = 8641516
227 + 8641289 = 8641516
269 + 8641247 = 8641516
383 + 8641133 = 8641516

Showing the first eight; more decompositions exist.
