Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931290, here are decompositions:

23 + 931267 = 931290
53 + 931237 = 931290
97 + 931193 = 931290
109 + 931181 = 931290
127 + 931163 = 931290
137 + 931153 = 931290
163 + 931127 = 931290
167 + 931123 = 931290

Showing the first eight; more decompositions exist.
