Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165474, here are decompositions:

5 + 165469 = 165474
11 + 165463 = 165474
17 + 165457 = 165474
31 + 165443 = 165474
37 + 165437 = 165474
83 + 165391 = 165474
107 + 165367 = 165474
131 + 165343 = 165474

Showing the first eight; more decompositions exist.
