Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660210, here are decompositions:

7 + 8660203 = 8660210
103 + 8660107 = 8660210
157 + 8660053 = 8660210
211 + 8659999 = 8660210
271 + 8659939 = 8660210
283 + 8659927 = 8660210
337 + 8659873 = 8660210
373 + 8659837 = 8660210

Showing the first eight; more decompositions exist.
