Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496322, here are decompositions:

5 + 31496317 = 31496322
29 + 31496293 = 31496322
59 + 31496263 = 31496322
61 + 31496261 = 31496322
101 + 31496221 = 31496322
103 + 31496219 = 31496322
113 + 31496209 = 31496322
149 + 31496173 = 31496322

Showing the first eight; more decompositions exist.
