Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700840, here are decompositions:

7 + 8700833 = 8700840
13 + 8700827 = 8700840
23 + 8700817 = 8700840
41 + 8700799 = 8700840
47 + 8700793 = 8700840
67 + 8700773 = 8700840
73 + 8700767 = 8700840
89 + 8700751 = 8700840

Showing the first eight; more decompositions exist.
