Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165394, here are decompositions:

3 + 165391 = 165394
11 + 165383 = 165394
83 + 165311 = 165394
101 + 165293 = 165394
107 + 165287 = 165394
191 + 165203 = 165394
233 + 165161 = 165394
311 + 165083 = 165394

Showing the first eight; more decompositions exist.
