Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931186, here are decompositions:

5 + 931181 = 931186
17 + 931169 = 931186
23 + 931163 = 931186
59 + 931127 = 931186
89 + 931097 = 931186
173 + 931013 = 931186
197 + 930989 = 931186
359 + 930827 = 931186

Showing the first eight; more decompositions exist.
