Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165286, here are decompositions:
- 53 + 165233 = 165286
- 83 + 165203 = 165286
- 113 + 165173 = 165286
- 197 + 165089 = 165286
- 227 + 165059 = 165286
- 239 + 165047 = 165286
- 449 + 164837 = 165286
- 557 + 164729 = 165286
Showing the first eight; more decompositions exist.
