Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162782, here are decompositions:

3 + 162779 = 162782
31 + 162751 = 162782
43 + 162739 = 162782
73 + 162709 = 162782
79 + 162703 = 162782
181 + 162601 = 162782
229 + 162553 = 162782
283 + 162499 = 162782

Showing the first eight; more decompositions exist.
