Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165330, here are decompositions:

13 + 165317 = 165330
17 + 165313 = 165330
19 + 165311 = 165330
37 + 165293 = 165330
43 + 165287 = 165330
83 + 165247 = 165330
97 + 165233 = 165330
101 + 165229 = 165330

Showing the first eight; more decompositions exist.
