Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165430, here are decompositions:

47 + 165383 = 165430
113 + 165317 = 165430
137 + 165293 = 165430
197 + 165233 = 165430
227 + 165203 = 165430
257 + 165173 = 165430
269 + 165161 = 165430
347 + 165083 = 165430

Showing the first eight; more decompositions exist.
