Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725872, here are decompositions:

31 + 8725841 = 8725872
41 + 8725831 = 8725872
59 + 8725813 = 8725872
73 + 8725799 = 8725872
139 + 8725733 = 8725872
173 + 8725699 = 8725872
191 + 8725681 = 8725872
229 + 8725643 = 8725872

Showing the first eight; more decompositions exist.
