Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589332, here are decompositions:

3 + 31589329 = 31589332
11 + 31589321 = 31589332
29 + 31589303 = 31589332
41 + 31589291 = 31589332
149 + 31589183 = 31589332
233 + 31589099 = 31589332
263 + 31589069 = 31589332
353 + 31588979 = 31589332

Showing the first eight; more decompositions exist.
