Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719826, here are decompositions:

7 + 8719819 = 8719826
13 + 8719813 = 8719826
79 + 8719747 = 8719826
127 + 8719699 = 8719826
163 + 8719663 = 8719826
223 + 8719603 = 8719826
277 + 8719549 = 8719826
307 + 8719519 = 8719826

Showing the first eight; more decompositions exist.
