Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42342, here are decompositions:
- 5 + 42337 = 42342
- 11 + 42331 = 42342
- 19 + 42323 = 42342
- 43 + 42299 = 42342
- 59 + 42283 = 42342
- 61 + 42281 = 42342
- 103 + 42239 = 42342
- 149 + 42193 = 42342
Showing the first eight; more decompositions exist.
