Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165278, here are decompositions:

31 + 165247 = 165278
67 + 165211 = 165278
97 + 165181 = 165278
199 + 165079 = 165278
229 + 165049 = 165278
241 + 165037 = 165278
277 + 165001 = 165278
367 + 164911 = 165278

Showing the first eight; more decompositions exist.
