Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601140, here are decompositions:

19 + 8601121 = 8601140
43 + 8601097 = 8601140
103 + 8601037 = 8601140
127 + 8601013 = 8601140
181 + 8600959 = 8601140
193 + 8600947 = 8601140
199 + 8600941 = 8601140
241 + 8600899 = 8601140

Showing the first eight; more decompositions exist.
