Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165782, here are decompositions:

3 + 165779 = 165782
61 + 165721 = 165782
73 + 165709 = 165782
79 + 165703 = 165782
109 + 165673 = 165782
181 + 165601 = 165782
193 + 165589 = 165782
223 + 165559 = 165782

Showing the first eight; more decompositions exist.
