Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663404, here are decompositions:

3 + 8663401 = 8663404
47 + 8663357 = 8663404
131 + 8663273 = 8663404
251 + 8663153 = 8663404
311 + 8663093 = 8663404
401 + 8663003 = 8663404
461 + 8662943 = 8663404
593 + 8662811 = 8663404

Showing the first eight; more decompositions exist.
