Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755666, here are decompositions:

47 + 8755619 = 8755666
53 + 8755613 = 8755666
107 + 8755559 = 8755666
137 + 8755529 = 8755666
149 + 8755517 = 8755666
167 + 8755499 = 8755666
197 + 8755469 = 8755666
317 + 8755349 = 8755666

Showing the first eight; more decompositions exist.
