Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931404, here are decompositions:

17 + 931387 = 931404
41 + 931363 = 931404
53 + 931351 = 931404
101 + 931303 = 931404
137 + 931267 = 931404
163 + 931241 = 931404
167 + 931237 = 931404
191 + 931213 = 931404

Showing the first eight; more decompositions exist.
