Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42368, here are decompositions:
- 19 + 42349 = 42368
- 31 + 42337 = 42368
- 37 + 42331 = 42368
- 61 + 42307 = 42368
- 181 + 42187 = 42368
- 199 + 42169 = 42368
- 211 + 42157 = 42368
- 229 + 42139 = 42368
Showing the first eight; more decompositions exist.
