Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725874, here are decompositions:

43 + 8725831 = 8725874
61 + 8725813 = 8725874
193 + 8725681 = 8725874
307 + 8725567 = 8725874
631 + 8725243 = 8725874
691 + 8725183 = 8725874
727 + 8725147 = 8725874
733 + 8725141 = 8725874

Showing the first eight; more decompositions exist.
