Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589896, here are decompositions:

5 + 31589891 = 31589896
29 + 31589867 = 31589896
53 + 31589843 = 31589896
137 + 31589759 = 31589896
263 + 31589633 = 31589896
383 + 31589513 = 31589896
557 + 31589339 = 31589896
563 + 31589333 = 31589896

Showing the first eight; more decompositions exist.
