Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756856, here are decompositions:

13 + 8756843 = 8756856
19 + 8756837 = 8756856
67 + 8756789 = 8756856
149 + 8756707 = 8756856
167 + 8756689 = 8756856
179 + 8756677 = 8756856
197 + 8756659 = 8756856
223 + 8756633 = 8756856

Showing the first eight; more decompositions exist.
