Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165450, here are decompositions:

7 + 165443 = 165450
13 + 165437 = 165450
53 + 165397 = 165450
59 + 165391 = 165450
67 + 165383 = 165450
71 + 165379 = 165450
83 + 165367 = 165450
101 + 165349 = 165450

Showing the first eight; more decompositions exist.
