Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660260, here are decompositions:

71 + 8660189 = 8660260
83 + 8660177 = 8660260
173 + 8660087 = 8660260
179 + 8660081 = 8660260
227 + 8660033 = 8660260
263 + 8659997 = 8660260
311 + 8659949 = 8660260
347 + 8659913 = 8660260

Showing the first eight; more decompositions exist.
