Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666652, here are decompositions:

61 + 8666591 = 8666652
109 + 8666543 = 8666652
139 + 8666513 = 8666652
151 + 8666501 = 8666652
173 + 8666479 = 8666652
193 + 8666459 = 8666652
233 + 8666419 = 8666652
271 + 8666381 = 8666652

Showing the first eight; more decompositions exist.
