Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700844, here are decompositions:

11 + 8700833 = 8700844
17 + 8700827 = 8700844
71 + 8700773 = 8700844
263 + 8700581 = 8700844
281 + 8700563 = 8700844
443 + 8700401 = 8700844
461 + 8700383 = 8700844
491 + 8700353 = 8700844

Showing the first eight; more decompositions exist.
