Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589950, here are decompositions:

59 + 31589891 = 31589950
83 + 31589867 = 31589950
89 + 31589861 = 31589950
107 + 31589843 = 31589950
131 + 31589819 = 31589950
173 + 31589777 = 31589950
179 + 31589771 = 31589950
191 + 31589759 = 31589950

Showing the first eight; more decompositions exist.
