Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725824, here are decompositions:

7 + 8725817 = 8725824
11 + 8725813 = 8725824
67 + 8725757 = 8725824
167 + 8725657 = 8725824
181 + 8725643 = 8725824
193 + 8725631 = 8725824
197 + 8725627 = 8725824
257 + 8725567 = 8725824

Showing the first eight; more decompositions exist.
