Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482010, here are decompositions:

29 + 31481981 = 31482010
59 + 31481951 = 31482010
71 + 31481939 = 31482010
89 + 31481921 = 31482010
167 + 31481843 = 31482010
173 + 31481837 = 31482010
179 + 31481831 = 31482010
191 + 31481819 = 31482010

Showing the first eight; more decompositions exist.
