Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165844, here are decompositions:

11 + 165833 = 165844
131 + 165713 = 165844
137 + 165707 = 165844
191 + 165653 = 165844
227 + 165617 = 165844
233 + 165611 = 165844
257 + 165587 = 165844
293 + 165551 = 165844

Showing the first eight; more decompositions exist.
