Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165608, here are decompositions:

7 + 165601 = 165608
19 + 165589 = 165608
67 + 165541 = 165608
97 + 165511 = 165608
139 + 165469 = 165608
151 + 165457 = 165608
211 + 165397 = 165608
229 + 165379 = 165608

Showing the first eight; more decompositions exist.
