Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165370, here are decompositions:

3 + 165367 = 165370
53 + 165317 = 165370
59 + 165311 = 165370
83 + 165287 = 165370
137 + 165233 = 165370
167 + 165203 = 165370
197 + 165173 = 165370
281 + 165089 = 165370

Showing the first eight; more decompositions exist.
