Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725850, here are decompositions:

19 + 8725831 = 8725850
37 + 8725813 = 8725850
151 + 8725699 = 8725850
181 + 8725669 = 8725850
193 + 8725657 = 8725850
223 + 8725627 = 8725850
229 + 8725621 = 8725850
241 + 8725609 = 8725850

Showing the first eight; more decompositions exist.
