Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165544, here are decompositions:

3 + 165541 = 165544
11 + 165533 = 165544
17 + 165527 = 165544
101 + 165443 = 165544
107 + 165437 = 165544
227 + 165317 = 165544
233 + 165311 = 165544
251 + 165293 = 165544

Showing the first eight; more decompositions exist.
