Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527322, here are decompositions:

5 + 31527317 = 31527322
11 + 31527311 = 31527322
89 + 31527233 = 31527322
131 + 31527191 = 31527322
149 + 31527173 = 31527322
173 + 31527149 = 31527322
179 + 31527143 = 31527322
191 + 31527131 = 31527322

Showing the first eight; more decompositions exist.
