Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641494, here are decompositions:

23 + 8641471 = 8641494
41 + 8641453 = 8641494
61 + 8641433 = 8641494
73 + 8641421 = 8641494
163 + 8641331 = 8641494
167 + 8641327 = 8641494
193 + 8641301 = 8641494
263 + 8641231 = 8641494

Showing the first eight; more decompositions exist.
