Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482074, here are decompositions:

7 + 31482067 = 31482074
31 + 31482043 = 31482074
37 + 31482037 = 31482074
61 + 31482013 = 31482074
163 + 31481911 = 31482074
223 + 31481851 = 31482074
307 + 31481767 = 31482074
331 + 31481743 = 31482074

Showing the first eight; more decompositions exist.
