Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598592, here are decompositions:

71 + 31598521 = 31598592
73 + 31598519 = 31598592
79 + 31598513 = 31598592
173 + 31598419 = 31598592
191 + 31598401 = 31598592
211 + 31598381 = 31598592
229 + 31598363 = 31598592
239 + 31598353 = 31598592

Showing the first eight; more decompositions exist.
