Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592382, here are decompositions:

5 + 31592377 = 31592382
13 + 31592369 = 31592382
71 + 31592311 = 31592382
163 + 31592219 = 31592382
179 + 31592203 = 31592382
223 + 31592159 = 31592382
233 + 31592149 = 31592382
331 + 31592051 = 31592382

Showing the first eight; more decompositions exist.
