Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165610, here are decompositions:

23 + 165587 = 165610
41 + 165569 = 165610
59 + 165551 = 165610
83 + 165527 = 165610
131 + 165479 = 165610
167 + 165443 = 165610
173 + 165437 = 165610
227 + 165383 = 165610

Showing the first eight; more decompositions exist.
