Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598896, here are decompositions:

23 + 31598873 = 31598896
29 + 31598867 = 31598896
107 + 31598789 = 31598896
113 + 31598783 = 31598896
179 + 31598717 = 31598896
227 + 31598669 = 31598896
353 + 31598543 = 31598896
359 + 31598537 = 31598896

Showing the first eight; more decompositions exist.
