Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660222, here are decompositions:

19 + 8660203 = 8660222
61 + 8660161 = 8660222
223 + 8659999 = 8660222
283 + 8659939 = 8660222
313 + 8659909 = 8660222
349 + 8659873 = 8660222
691 + 8659531 = 8660222
709 + 8659513 = 8660222

Showing the first eight; more decompositions exist.
