Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931080, here are decompositions:

13 + 931067 = 931080
67 + 931013 = 931080
89 + 930991 = 931080
103 + 930977 = 931080
107 + 930973 = 931080
149 + 930931 = 931080
191 + 930889 = 931080
233 + 930847 = 931080

Showing the first eight; more decompositions exist.
