Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165432, here are decompositions:

41 + 165391 = 165432
53 + 165379 = 165432
83 + 165349 = 165432
89 + 165343 = 165432
101 + 165331 = 165432
139 + 165293 = 165432
199 + 165233 = 165432
229 + 165203 = 165432

Showing the first eight; more decompositions exist.
