Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725716, here are decompositions:

17 + 8725699 = 8725716
47 + 8725669 = 8725716
59 + 8725657 = 8725716
73 + 8725643 = 8725716
89 + 8725627 = 8725716
107 + 8725609 = 8725716
149 + 8725567 = 8725716
193 + 8725523 = 8725716

Showing the first eight; more decompositions exist.
