Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532982, here are decompositions:

11 + 31532971 = 31532982
23 + 31532959 = 31532982
43 + 31532939 = 31532982
59 + 31532923 = 31532982
83 + 31532899 = 31532982
101 + 31532881 = 31532982
109 + 31532873 = 31532982
149 + 31532833 = 31532982

Showing the first eight; more decompositions exist.
