Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161848, here are decompositions:
- 17 + 161831 = 161848
- 41 + 161807 = 161848
- 107 + 161741 = 161848
- 131 + 161717 = 161848
- 257 + 161591 = 161848
- 317 + 161531 = 161848
- 389 + 161459 = 161848
- 461 + 161387 = 161848
Showing the first eight; more decompositions exist.
