Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31570896, here are decompositions:

23 + 31570873 = 31570896
29 + 31570867 = 31570896
37 + 31570859 = 31570896
53 + 31570843 = 31570896
67 + 31570829 = 31570896
79 + 31570817 = 31570896
109 + 31570787 = 31570896
139 + 31570757 = 31570896

Showing the first eight; more decompositions exist.
