Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165994, here are decompositions:

11 + 165983 = 165994
47 + 165947 = 165994
53 + 165941 = 165994
107 + 165887 = 165994
137 + 165857 = 165994
281 + 165713 = 165994
293 + 165701 = 165994
383 + 165611 = 165994

Showing the first eight; more decompositions exist.
