Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673828, here are decompositions:

11 + 8673817 = 8673828
47 + 8673781 = 8673828
67 + 8673761 = 8673828
101 + 8673727 = 8673828
151 + 8673677 = 8673828
227 + 8673601 = 8673828
257 + 8673571 = 8673828
281 + 8673547 = 8673828

Showing the first eight; more decompositions exist.
