Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931188, here are decompositions:

7 + 931181 = 931188
19 + 931169 = 931188
59 + 931129 = 931188
61 + 931127 = 931188
101 + 931087 = 931188
197 + 930991 = 931188
199 + 930989 = 931188
211 + 930977 = 931188

Showing the first eight; more decompositions exist.
