Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638552, here are decompositions:

71 + 8638481 = 8638552
89 + 8638463 = 8638552
101 + 8638451 = 8638552
149 + 8638403 = 8638552
173 + 8638379 = 8638552
179 + 8638373 = 8638552
233 + 8638319 = 8638552
269 + 8638283 = 8638552

Showing the first eight; more decompositions exist.
