Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165492, here are decompositions:

13 + 165479 = 165492
23 + 165469 = 165492
29 + 165463 = 165492
43 + 165449 = 165492
101 + 165391 = 165492
109 + 165383 = 165492
113 + 165379 = 165492
149 + 165343 = 165492

Showing the first eight; more decompositions exist.
