Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8660278, here are decompositions:

89 + 8660189 = 8660278
101 + 8660177 = 8660278
191 + 8660087 = 8660278
197 + 8660081 = 8660278
227 + 8660051 = 8660278
239 + 8660039 = 8660278
281 + 8659997 = 8660278
467 + 8659811 = 8660278

Showing the first eight; more decompositions exist.
