Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165486, here are decompositions:
- 7 + 165479 = 165486
- 17 + 165469 = 165486
- 23 + 165463 = 165486
- 29 + 165457 = 165486
- 37 + 165449 = 165486
- 43 + 165443 = 165486
- 89 + 165397 = 165486
- 103 + 165383 = 165486
Showing the first eight; more decompositions exist.
