Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648840, here are decompositions:

3 + 8648837 = 8648840
7 + 8648833 = 8648840
43 + 8648797 = 8648840
61 + 8648779 = 8648840
103 + 8648737 = 8648840
139 + 8648701 = 8648840
163 + 8648677 = 8648840
283 + 8648557 = 8648840

Showing the first eight; more decompositions exist.
