Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539592, here are decompositions:

5 + 31539587 = 31539592
23 + 31539569 = 31539592
179 + 31539413 = 31539592
191 + 31539401 = 31539592
239 + 31539353 = 31539592
263 + 31539329 = 31539592
401 + 31539191 = 31539592
449 + 31539143 = 31539592

Showing the first eight; more decompositions exist.
