Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165360, here are decompositions:
- 11 + 165349 = 165360
- 17 + 165343 = 165360
- 29 + 165331 = 165360
- 43 + 165317 = 165360
- 47 + 165313 = 165360
- 67 + 165293 = 165360
- 73 + 165287 = 165360
- 113 + 165247 = 165360
Showing the first eight; more decompositions exist.
