Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660120, here are decompositions:

13 + 8660107 = 8660120
43 + 8660077 = 8660120
67 + 8660053 = 8660120
163 + 8659957 = 8660120
181 + 8659939 = 8660120
193 + 8659927 = 8660120
199 + 8659921 = 8660120
211 + 8659909 = 8660120

Showing the first eight; more decompositions exist.
