Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8755638, here are decompositions:

19 + 8755619 = 8755638
37 + 8755601 = 8755638
79 + 8755559 = 8755638
109 + 8755529 = 8755638
137 + 8755501 = 8755638
139 + 8755499 = 8755638
239 + 8755399 = 8755638
257 + 8755381 = 8755638

Showing the first eight; more decompositions exist.
