Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165028, here are decompositions:

29 + 164999 = 165028
41 + 164987 = 165028
191 + 164837 = 165028
197 + 164831 = 165028
239 + 164789 = 165028
257 + 164771 = 165028
401 + 164627 = 165028
557 + 164471 = 165028

Showing the first eight; more decompositions exist.
