Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562322, here are decompositions:

23 + 31562299 = 31562322
31 + 31562291 = 31562322
41 + 31562281 = 31562322
59 + 31562263 = 31562322
61 + 31562261 = 31562322
79 + 31562243 = 31562322
109 + 31562213 = 31562322
223 + 31562099 = 31562322

Showing the first eight; more decompositions exist.
