Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660220, here are decompositions:

17 + 8660203 = 8660220
31 + 8660189 = 8660220
43 + 8660177 = 8660220
59 + 8660161 = 8660220
113 + 8660107 = 8660220
139 + 8660081 = 8660220
167 + 8660053 = 8660220
181 + 8660039 = 8660220

Showing the first eight; more decompositions exist.
