Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931180, here are decompositions:

11 + 931169 = 931180
17 + 931163 = 931180
53 + 931127 = 931180
83 + 931097 = 931180
113 + 931067 = 931180
167 + 931013 = 931180
191 + 930989 = 931180
269 + 930911 = 931180

Showing the first eight; more decompositions exist.
