Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690404, here are decompositions:

5 + 8690399 = 8690404
17 + 8690387 = 8690404
53 + 8690351 = 8690404
71 + 8690333 = 8690404
101 + 8690303 = 8690404
113 + 8690291 = 8690404
137 + 8690267 = 8690404
227 + 8690177 = 8690404

Showing the first eight; more decompositions exist.
