Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664666, here are decompositions:

5 + 8664661 = 8664666
53 + 8664613 = 8664666
107 + 8664559 = 8664666
113 + 8664553 = 8664666
137 + 8664529 = 8664666
139 + 8664527 = 8664666
149 + 8664517 = 8664666
193 + 8664473 = 8664666

Showing the first eight; more decompositions exist.
