Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482018, here are decompositions:

5 + 31482013 = 31482018
37 + 31481981 = 31482018
67 + 31481951 = 31482018
79 + 31481939 = 31482018
97 + 31481921 = 31482018
107 + 31481911 = 31482018
131 + 31481887 = 31482018
151 + 31481867 = 31482018

Showing the first eight; more decompositions exist.
