Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712256, here are decompositions:

23 + 8712233 = 8712256
29 + 8712227 = 8712256
83 + 8712173 = 8712256
89 + 8712167 = 8712256
107 + 8712149 = 8712256
197 + 8712059 = 8712256
227 + 8712029 = 8712256
239 + 8712017 = 8712256

Showing the first eight; more decompositions exist.
