Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589874, here are decompositions:

5 + 31589869 = 31589874
7 + 31589867 = 31589874
13 + 31589861 = 31589874
31 + 31589843 = 31589874
47 + 31589827 = 31589874
97 + 31589777 = 31589874
101 + 31589773 = 31589874
103 + 31589771 = 31589874

Showing the first eight; more decompositions exist.
