Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42434, here are decompositions:
- 31 + 42403 = 42434
- 37 + 42397 = 42434
- 43 + 42391 = 42434
- 61 + 42373 = 42434
- 97 + 42337 = 42434
- 103 + 42331 = 42434
- 127 + 42307 = 42434
- 151 + 42283 = 42434
Showing the first eight; more decompositions exist.
