Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582944, here are decompositions:

7 + 31582937 = 31582944
13 + 31582931 = 31582944
31 + 31582913 = 31582944
37 + 31582907 = 31582944
47 + 31582897 = 31582944
53 + 31582891 = 31582944
97 + 31582847 = 31582944
163 + 31582781 = 31582944

Showing the first eight; more decompositions exist.
