Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532964, here are decompositions:

5 + 31532959 = 31532964
41 + 31532923 = 31532964
83 + 31532881 = 31532964
97 + 31532867 = 31532964
101 + 31532863 = 31532964
131 + 31532833 = 31532964
227 + 31532737 = 31532964
271 + 31532693 = 31532964

Showing the first eight; more decompositions exist.
