Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589970, here are decompositions:

17 + 31589953 = 31589970
47 + 31589923 = 31589970
79 + 31589891 = 31589970
101 + 31589869 = 31589970
103 + 31589867 = 31589970
109 + 31589861 = 31589970
127 + 31589843 = 31589970
151 + 31589819 = 31589970

Showing the first eight; more decompositions exist.
