Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681844, here are decompositions:

7 + 8681837 = 8681844
13 + 8681831 = 8681844
23 + 8681821 = 8681844
107 + 8681737 = 8681844
113 + 8681731 = 8681844
137 + 8681707 = 8681844
151 + 8681693 = 8681844
181 + 8681663 = 8681844

Showing the first eight; more decompositions exist.
