Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665552, here are decompositions:

11 + 8665541 = 8665552
53 + 8665499 = 8665552
83 + 8665469 = 8665552
101 + 8665451 = 8665552
179 + 8665373 = 8665552
191 + 8665361 = 8665552
239 + 8665313 = 8665552
293 + 8665259 = 8665552

Showing the first eight; more decompositions exist.
