Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165732, here are decompositions:

11 + 165721 = 165732
13 + 165719 = 165732
19 + 165713 = 165732
23 + 165709 = 165732
29 + 165703 = 165732
31 + 165701 = 165732
59 + 165673 = 165732
79 + 165653 = 165732

Showing the first eight; more decompositions exist.
