Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592452, here are decompositions:

5 + 31592447 = 31592452
29 + 31592423 = 31592452
41 + 31592411 = 31592452
83 + 31592369 = 31592452
233 + 31592219 = 31592452
239 + 31592213 = 31592452
293 + 31592159 = 31592452
401 + 31592051 = 31592452

Showing the first eight; more decompositions exist.
