Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532934, here are decompositions:

11 + 31532923 = 31532934
53 + 31532881 = 31532934
61 + 31532873 = 31532934
67 + 31532867 = 31532934
71 + 31532863 = 31532934
101 + 31532833 = 31532934
157 + 31532777 = 31532934
197 + 31532737 = 31532934

Showing the first eight; more decompositions exist.
