Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931158, here are decompositions:

5 + 931153 = 931158
29 + 931129 = 931158
31 + 931127 = 931158
61 + 931097 = 931158
71 + 931087 = 931158
167 + 930991 = 931158
181 + 930977 = 931158
227 + 930931 = 931158

Showing the first eight; more decompositions exist.
