Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523322, here are decompositions:

13 + 31523309 = 31523322
29 + 31523293 = 31523322
43 + 31523279 = 31523322
71 + 31523251 = 31523322
79 + 31523243 = 31523322
101 + 31523221 = 31523322
113 + 31523209 = 31523322
179 + 31523143 = 31523322

Showing the first eight; more decompositions exist.
