Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165250, here are decompositions:

3 + 165247 = 165250
17 + 165233 = 165250
47 + 165203 = 165250
89 + 165161 = 165250
167 + 165083 = 165250
191 + 165059 = 165250
251 + 164999 = 165250
263 + 164987 = 165250

Showing the first eight; more decompositions exist.
