Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646824, here are decompositions:

3 + 8646821 = 8646824
7 + 8646817 = 8646824
31 + 8646793 = 8646824
73 + 8646751 = 8646824
103 + 8646721 = 8646824
157 + 8646667 = 8646824
313 + 8646511 = 8646824
337 + 8646487 = 8646824

Showing the first eight; more decompositions exist.
