Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165412, here are decompositions:

29 + 165383 = 165412
101 + 165311 = 165412
179 + 165233 = 165412
239 + 165173 = 165412
251 + 165161 = 165412
353 + 165059 = 165412
449 + 164963 = 165412
641 + 164771 = 165412

Showing the first eight; more decompositions exist.
