Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756644, here are decompositions:

11 + 8756633 = 8756644
53 + 8756591 = 8756644
137 + 8756507 = 8756644
173 + 8756471 = 8756644
251 + 8756393 = 8756644
263 + 8756381 = 8756644
311 + 8756333 = 8756644
431 + 8756213 = 8756644

Showing the first eight; more decompositions exist.
