Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589884, here are decompositions:

17 + 31589867 = 31589884
23 + 31589861 = 31589884
41 + 31589843 = 31589884
107 + 31589777 = 31589884
113 + 31589771 = 31589884
173 + 31589711 = 31589884
191 + 31589693 = 31589884
251 + 31589633 = 31589884

Showing the first eight; more decompositions exist.
