Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648880, here are decompositions:

13 + 8648867 = 8648880
17 + 8648863 = 8648880
41 + 8648839 = 8648880
43 + 8648837 = 8648880
47 + 8648833 = 8648880
67 + 8648813 = 8648880
83 + 8648797 = 8648880
89 + 8648791 = 8648880

Showing the first eight; more decompositions exist.
