Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520964, here are decompositions:

5 + 31520959 = 31520964
47 + 31520917 = 31520964
53 + 31520911 = 31520964
67 + 31520897 = 31520964
103 + 31520861 = 31520964
107 + 31520857 = 31520964
113 + 31520851 = 31520964
127 + 31520837 = 31520964

Showing the first eight; more decompositions exist.
