Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646404, here are decompositions:

3 + 8646401 = 8646404
43 + 8646361 = 8646404
127 + 8646277 = 8646404
157 + 8646247 = 8646404
181 + 8646223 = 8646404
223 + 8646181 = 8646404
241 + 8646163 = 8646404
433 + 8645971 = 8646404

Showing the first eight; more decompositions exist.
