Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532956, here are decompositions:

17 + 31532939 = 31532956
83 + 31532873 = 31532956
89 + 31532867 = 31532956
179 + 31532777 = 31532956
263 + 31532693 = 31532956
269 + 31532687 = 31532956
317 + 31532639 = 31532956
359 + 31532597 = 31532956

Showing the first eight; more decompositions exist.
