Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165508, here are decompositions:

29 + 165479 = 165508
59 + 165449 = 165508
71 + 165437 = 165508
191 + 165317 = 165508
197 + 165311 = 165508
347 + 165161 = 165508
419 + 165089 = 165508
449 + 165059 = 165508

Showing the first eight; more decompositions exist.
