Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42384, here are decompositions:
- 5 + 42379 = 42384
- 11 + 42373 = 42384
- 47 + 42337 = 42384
- 53 + 42331 = 42384
- 61 + 42323 = 42384
- 101 + 42283 = 42384
- 103 + 42281 = 42384
- 127 + 42257 = 42384
Showing the first eight; more decompositions exist.
