Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660244, here are decompositions:

11 + 8660233 = 8660244
17 + 8660227 = 8660244
23 + 8660221 = 8660244
41 + 8660203 = 8660244
67 + 8660177 = 8660244
83 + 8660161 = 8660244
137 + 8660107 = 8660244
157 + 8660087 = 8660244

Showing the first eight; more decompositions exist.
