Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636856, here are decompositions:

17 + 8636839 = 8636856
37 + 8636819 = 8636856
97 + 8636759 = 8636856
167 + 8636689 = 8636856
223 + 8636633 = 8636856
229 + 8636627 = 8636856
257 + 8636599 = 8636856
269 + 8636587 = 8636856

Showing the first eight; more decompositions exist.
