Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648894, here are decompositions:

13 + 8648881 = 8648894
31 + 8648863 = 8648894
61 + 8648833 = 8648894
97 + 8648797 = 8648894
103 + 8648791 = 8648894
157 + 8648737 = 8648894
193 + 8648701 = 8648894
337 + 8648557 = 8648894

Showing the first eight; more decompositions exist.
