Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31595968, here are decompositions:

101 + 31595867 = 31595968
137 + 31595831 = 31595968
191 + 31595777 = 31595968
197 + 31595771 = 31595968
251 + 31595717 = 31595968
281 + 31595687 = 31595968
311 + 31595657 = 31595968
401 + 31595567 = 31595968

Showing the first eight; more decompositions exist.
