Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42432, here are decompositions:
- 23 + 42409 = 42432
- 29 + 42403 = 42432
- 41 + 42391 = 42432
- 53 + 42379 = 42432
- 59 + 42373 = 42432
- 73 + 42359 = 42432
- 83 + 42349 = 42432
- 101 + 42331 = 42432
Showing the first eight; more decompositions exist.
