Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165982, here are decompositions:

41 + 165941 = 165982
149 + 165833 = 165982
233 + 165749 = 165982
263 + 165719 = 165982
269 + 165713 = 165982
281 + 165701 = 165982
431 + 165551 = 165982
449 + 165533 = 165982

Showing the first eight; more decompositions exist.
