Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660250, here are decompositions:

17 + 8660233 = 8660250
23 + 8660227 = 8660250
29 + 8660221 = 8660250
47 + 8660203 = 8660250
61 + 8660189 = 8660250
73 + 8660177 = 8660250
89 + 8660161 = 8660250
163 + 8660087 = 8660250

Showing the first eight; more decompositions exist.
