Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646928, here are decompositions:

29 + 8646899 = 8646928
107 + 8646821 = 8646928
149 + 8646779 = 8646928
347 + 8646581 = 8646928
431 + 8646497 = 8646928
449 + 8646479 = 8646928
599 + 8646329 = 8646928
659 + 8646269 = 8646928

Showing the first eight; more decompositions exist.
