Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626826, here are decompositions:

3 + 8626823 = 8626826
7 + 8626819 = 8626826
79 + 8626747 = 8626826
127 + 8626699 = 8626826
157 + 8626669 = 8626826
223 + 8626603 = 8626826
277 + 8626549 = 8626826
367 + 8626459 = 8626826

Showing the first eight; more decompositions exist.
