Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622666, here are decompositions:

89 + 8622577 = 8622666
103 + 8622563 = 8622666
137 + 8622529 = 8622666
167 + 8622499 = 8622666
179 + 8622487 = 8622666
193 + 8622473 = 8622666
197 + 8622469 = 8622666
293 + 8622373 = 8622666

Showing the first eight; more decompositions exist.
