Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720956, here are decompositions:

3 + 8720953 = 8720956
137 + 8720819 = 8720956
149 + 8720807 = 8720956
173 + 8720783 = 8720956
227 + 8720729 = 8720956
263 + 8720693 = 8720956
269 + 8720687 = 8720956
359 + 8720597 = 8720956

Showing the first eight; more decompositions exist.
