Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728726, here are decompositions:

5 + 8728721 = 8728726
47 + 8728679 = 8728726
269 + 8728457 = 8728726
353 + 8728373 = 8728726
557 + 8728169 = 8728726
647 + 8728079 = 8728726
653 + 8728073 = 8728726
827 + 8727899 = 8728726

Showing the first eight; more decompositions exist.
