Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756872, here are decompositions:

29 + 8756843 = 8756872
83 + 8756789 = 8756872
101 + 8756771 = 8756872
239 + 8756633 = 8756872
263 + 8756609 = 8756872
281 + 8756591 = 8756872
353 + 8756519 = 8756872
401 + 8756471 = 8756872

Showing the first eight; more decompositions exist.
