Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598164, here are decompositions:

23 + 31598141 = 31598164
107 + 31598057 = 31598164
131 + 31598033 = 31598164
137 + 31598027 = 31598164
167 + 31597997 = 31598164
251 + 31597913 = 31598164
401 + 31597763 = 31598164
443 + 31597721 = 31598164

Showing the first eight; more decompositions exist.
