Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482030, here are decompositions:

17 + 31482013 = 31482030
79 + 31481951 = 31482030
109 + 31481921 = 31482030
131 + 31481899 = 31482030
163 + 31481867 = 31482030
179 + 31481851 = 31482030
193 + 31481837 = 31482030
199 + 31481831 = 31482030

Showing the first eight; more decompositions exist.
