Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482012, here are decompositions:

31 + 31481981 = 31482012
61 + 31481951 = 31482012
73 + 31481939 = 31482012
101 + 31481911 = 31482012
113 + 31481899 = 31482012
181 + 31481831 = 31482012
193 + 31481819 = 31482012
269 + 31481743 = 31482012

Showing the first eight; more decompositions exist.
