Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532884, here are decompositions:

3 + 31532881 = 31532884
11 + 31532873 = 31532884
17 + 31532867 = 31532884
107 + 31532777 = 31532884
191 + 31532693 = 31532884
197 + 31532687 = 31532884
311 + 31532573 = 31532884
743 + 31532141 = 31532884

Showing the first eight; more decompositions exist.
