Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589968, here are decompositions:

101 + 31589867 = 31589968
107 + 31589861 = 31589968
149 + 31589819 = 31589968
191 + 31589777 = 31589968
197 + 31589771 = 31589968
257 + 31589711 = 31589968
401 + 31589567 = 31589968
647 + 31589321 = 31589968

Showing the first eight; more decompositions exist.
