Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31322, here are decompositions:

3 + 31319 = 31322
73 + 31249 = 31322
103 + 31219 = 31322
139 + 31183 = 31322
163 + 31159 = 31322
199 + 31123 = 31322
241 + 31081 = 31322
271 + 31051 = 31322

Showing the first eight; more decompositions exist.
