Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592932, here are decompositions:

11 + 31592921 = 31592932
83 + 31592849 = 31592932
89 + 31592843 = 31592932
269 + 31592663 = 31592932
281 + 31592651 = 31592932
311 + 31592621 = 31592932
401 + 31592531 = 31592932
443 + 31592489 = 31592932

Showing the first eight; more decompositions exist.
