Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523392, here are decompositions:

11 + 31523381 = 31523392
83 + 31523309 = 31523392
113 + 31523279 = 31523392
149 + 31523243 = 31523392
191 + 31523201 = 31523392
281 + 31523111 = 31523392
293 + 31523099 = 31523392
311 + 31523081 = 31523392

Showing the first eight; more decompositions exist.
