Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178782, here are decompositions:

29 + 178753 = 178782
89 + 178693 = 178782
101 + 178681 = 178782
139 + 178643 = 178782
173 + 178609 = 178782
179 + 178603 = 178782
181 + 178601 = 178782
211 + 178571 = 178782

Showing the first eight; more decompositions exist.
