Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725916, here are decompositions:

103 + 8725813 = 8725916
307 + 8725609 = 8725916
349 + 8725567 = 8725916
457 + 8725459 = 8725916
487 + 8725429 = 8725916
673 + 8725243 = 8725916
709 + 8725207 = 8725916
733 + 8725183 = 8725916

Showing the first eight; more decompositions exist.
