Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188404, here are decompositions:

3 + 188401 = 188404
53 + 188351 = 188404
71 + 188333 = 188404
101 + 188303 = 188404
113 + 188291 = 188404
131 + 188273 = 188404
233 + 188171 = 188404
257 + 188147 = 188404

Showing the first eight; more decompositions exist.
