Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165226, here are decompositions:

23 + 165203 = 165226
53 + 165173 = 165226
137 + 165089 = 165226
167 + 165059 = 165226
179 + 165047 = 165226
227 + 164999 = 165226
239 + 164987 = 165226
263 + 164963 = 165226

Showing the first eight; more decompositions exist.
