Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725844, here are decompositions:

3 + 8725841 = 8725844
13 + 8725831 = 8725844
31 + 8725813 = 8725844
163 + 8725681 = 8725844
223 + 8725621 = 8725844
277 + 8725567 = 8725844
313 + 8725531 = 8725844
487 + 8725357 = 8725844

Showing the first eight; more decompositions exist.
