Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756440, here are decompositions:

3 + 8756437 = 8756440
47 + 8756393 = 8756440
59 + 8756381 = 8756440
83 + 8756357 = 8756440
107 + 8756333 = 8756440
227 + 8756213 = 8756440
239 + 8756201 = 8756440
281 + 8756159 = 8756440

Showing the first eight; more decompositions exist.
