Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646648, here are decompositions:

41 + 8646607 = 8646648
67 + 8646581 = 8646648
89 + 8646559 = 8646648
137 + 8646511 = 8646648
151 + 8646497 = 8646648
191 + 8646457 = 8646648
271 + 8646377 = 8646648
331 + 8646317 = 8646648

Showing the first eight; more decompositions exist.
