Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45842, here are decompositions:
- 19 + 45823 = 45842
- 79 + 45763 = 45842
- 151 + 45691 = 45842
- 211 + 45631 = 45842
- 229 + 45613 = 45842
- 409 + 45433 = 45842
- 439 + 45403 = 45842
- 499 + 45343 = 45842
Showing the first eight; more decompositions exist.
