Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17882, here are decompositions:

19 + 17863 = 17882
31 + 17851 = 17882
43 + 17839 = 17882
199 + 17683 = 17882
223 + 17659 = 17882
283 + 17599 = 17882
313 + 17569 = 17882
331 + 17551 = 17882

Showing the first eight; more decompositions exist.
