Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179782, here are decompositions:

3 + 179779 = 179782
89 + 179693 = 179782
131 + 179651 = 179782
149 + 179633 = 179782
179 + 179603 = 179782
191 + 179591 = 179782
233 + 179549 = 179782
263 + 179519 = 179782

Showing the first eight; more decompositions exist.
