Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532946, here are decompositions:

7 + 31532939 = 31532946
23 + 31532923 = 31532946
47 + 31532899 = 31532946
73 + 31532873 = 31532946
79 + 31532867 = 31532946
83 + 31532863 = 31532946
113 + 31532833 = 31532946
197 + 31532749 = 31532946

Showing the first eight; more decompositions exist.
