Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626874, here are decompositions:

13 + 8626861 = 8626874
43 + 8626831 = 8626874
73 + 8626801 = 8626874
97 + 8626777 = 8626874
127 + 8626747 = 8626874
271 + 8626603 = 8626874
367 + 8626507 = 8626874
457 + 8626417 = 8626874

Showing the first eight; more decompositions exist.
