Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931172, here are decompositions:

3 + 931169 = 931172
19 + 931153 = 931172
43 + 931129 = 931172
181 + 930991 = 931172
199 + 930973 = 931172
241 + 930931 = 931172
283 + 930889 = 931172
313 + 930859 = 931172

Showing the first eight; more decompositions exist.
