Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482080, here are decompositions:

13 + 31482067 = 31482080
37 + 31482043 = 31482080
43 + 31482037 = 31482080
67 + 31482013 = 31482080
181 + 31481899 = 31482080
193 + 31481887 = 31482080
229 + 31481851 = 31482080
313 + 31481767 = 31482080

Showing the first eight; more decompositions exist.
