Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008866, here are decompositions:

3 + 1008863 = 1008866
7 + 1008859 = 1008866
13 + 1008853 = 1008866
37 + 1008829 = 1008866
73 + 1008793 = 1008866
277 + 1008589 = 1008866
349 + 1008517 = 1008866
367 + 1008499 = 1008866

Showing the first eight; more decompositions exist.
