Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592248, here are decompositions:

29 + 31592219 = 31592248
89 + 31592159 = 31592248
197 + 31592051 = 31592248
251 + 31591997 = 31592248
269 + 31591979 = 31592248
509 + 31591739 = 31592248
599 + 31591649 = 31592248
647 + 31591601 = 31592248

Showing the first eight; more decompositions exist.
