Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646444, here are decompositions:

41 + 8646403 = 8646444
43 + 8646401 = 8646444
67 + 8646377 = 8646444
83 + 8646361 = 8646444
127 + 8646317 = 8646444
151 + 8646293 = 8646444
167 + 8646277 = 8646444
197 + 8646247 = 8646444

Showing the first eight; more decompositions exist.
