Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592322, here are decompositions:

11 + 31592311 = 31592322
31 + 31592291 = 31592322
103 + 31592219 = 31592322
109 + 31592213 = 31592322
149 + 31592173 = 31592322
163 + 31592159 = 31592322
173 + 31592149 = 31592322
193 + 31592129 = 31592322

Showing the first eight; more decompositions exist.
