Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666662, here are decompositions:

71 + 8666591 = 8666662
149 + 8666513 = 8666662
269 + 8666393 = 8666662
281 + 8666381 = 8666662
293 + 8666369 = 8666662
311 + 8666351 = 8666662
443 + 8666219 = 8666662
461 + 8666201 = 8666662

Showing the first eight; more decompositions exist.
