Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931128, here are decompositions:

5 + 931123 = 931128
31 + 931097 = 931128
41 + 931087 = 931128
61 + 931067 = 931128
137 + 930991 = 931128
139 + 930989 = 931128
151 + 930977 = 931128
197 + 930931 = 931128

Showing the first eight; more decompositions exist.
