Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165268, here are decompositions:

107 + 165161 = 165268
179 + 165089 = 165268
227 + 165041 = 165268
269 + 164999 = 165268
281 + 164987 = 165268
431 + 164837 = 165268
479 + 164789 = 165268
641 + 164627 = 165268

Showing the first eight; more decompositions exist.
