Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931140, here are decompositions:

11 + 931129 = 931140
13 + 931127 = 931140
17 + 931123 = 931140
43 + 931097 = 931140
53 + 931087 = 931140
73 + 931067 = 931140
127 + 931013 = 931140
137 + 931003 = 931140

Showing the first eight; more decompositions exist.
