Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165396, here are decompositions:

5 + 165391 = 165396
13 + 165383 = 165396
17 + 165379 = 165396
29 + 165367 = 165396
47 + 165349 = 165396
53 + 165343 = 165396
79 + 165317 = 165396
83 + 165313 = 165396

Showing the first eight; more decompositions exist.
