Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589322, here are decompositions:

5 + 31589317 = 31589322
19 + 31589303 = 31589322
29 + 31589293 = 31589322
31 + 31589291 = 31589322
71 + 31589251 = 31589322
139 + 31589183 = 31589322
223 + 31589099 = 31589322
311 + 31589011 = 31589322

Showing the first eight; more decompositions exist.
