Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165646, here are decompositions:

29 + 165617 = 165646
59 + 165587 = 165646
113 + 165533 = 165646
167 + 165479 = 165646
197 + 165449 = 165646
263 + 165383 = 165646
353 + 165293 = 165646
359 + 165287 = 165646

Showing the first eight; more decompositions exist.
