Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931018, here are decompositions:

5 + 931013 = 931018
29 + 930989 = 931018
41 + 930977 = 931018
107 + 930911 = 931018
191 + 930827 = 931018
239 + 930779 = 931018
269 + 930749 = 931018
281 + 930737 = 931018

Showing the first eight; more decompositions exist.
