Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589298, here are decompositions:

5 + 31589293 = 31589298
7 + 31589291 = 31589298
11 + 31589287 = 31589298
47 + 31589251 = 31589298
101 + 31589197 = 31589298
131 + 31589167 = 31589298
179 + 31589119 = 31589298
199 + 31589099 = 31589298

Showing the first eight; more decompositions exist.
