Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626844, here are decompositions:

3 + 8626841 = 8626844
13 + 8626831 = 8626844
43 + 8626801 = 8626844
67 + 8626777 = 8626844
97 + 8626747 = 8626844
223 + 8626621 = 8626844
241 + 8626603 = 8626844
337 + 8626507 = 8626844

Showing the first eight; more decompositions exist.
