Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165588, here are decompositions:
- 19 + 165569 = 165588
- 29 + 165559 = 165588
- 37 + 165551 = 165588
- 47 + 165541 = 165588
- 61 + 165527 = 165588
- 109 + 165479 = 165588
- 131 + 165457 = 165588
- 139 + 165449 = 165588
Showing the first eight; more decompositions exist.
