Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165248, here are decompositions:

19 + 165229 = 165248
37 + 165211 = 165248
67 + 165181 = 165248
199 + 165049 = 165248
211 + 165037 = 165248
337 + 164911 = 165248
367 + 164881 = 165248
409 + 164839 = 165248

Showing the first eight; more decompositions exist.
