Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018404, here are decompositions:

47 + 1018357 = 1018404
67 + 1018337 = 1018404
103 + 1018301 = 1018404
113 + 1018291 = 1018404
151 + 1018253 = 1018404
157 + 1018247 = 1018404
181 + 1018223 = 1018404
197 + 1018207 = 1018404

Showing the first eight; more decompositions exist.
