Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165522, here are decompositions:

11 + 165511 = 165522
43 + 165479 = 165522
53 + 165469 = 165522
59 + 165463 = 165522
73 + 165449 = 165522
79 + 165443 = 165522
131 + 165391 = 165522
139 + 165383 = 165522

Showing the first eight; more decompositions exist.
