Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641404, here are decompositions:

43 + 8641361 = 8641404
53 + 8641351 = 8641404
73 + 8641331 = 8641404
103 + 8641301 = 8641404
131 + 8641273 = 8641404
157 + 8641247 = 8641404
173 + 8641231 = 8641404
193 + 8641211 = 8641404

Showing the first eight; more decompositions exist.
