Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178882, here are decompositions:

5 + 178877 = 178882
23 + 178859 = 178882
29 + 178853 = 178882
83 + 178799 = 178882
89 + 178793 = 178882
101 + 178781 = 178882
191 + 178691 = 178882
239 + 178643 = 178882

Showing the first eight; more decompositions exist.
