Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726826, here are decompositions:

23 + 8726803 = 8726826
37 + 8726789 = 8726826
67 + 8726759 = 8726826
89 + 8726737 = 8726826
103 + 8726723 = 8726826
113 + 8726713 = 8726826
127 + 8726699 = 8726826
139 + 8726687 = 8726826

Showing the first eight; more decompositions exist.
