Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726816, here are decompositions:

13 + 8726803 = 8726816
79 + 8726737 = 8726816
103 + 8726713 = 8726816
139 + 8726677 = 8726816
229 + 8726587 = 8726816
283 + 8726533 = 8726816
337 + 8726479 = 8726816
349 + 8726467 = 8726816

Showing the first eight; more decompositions exist.
