Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42380, here are decompositions:
- 7 + 42373 = 42380
- 31 + 42349 = 42380
- 43 + 42337 = 42380
- 73 + 42307 = 42380
- 97 + 42283 = 42380
- 157 + 42223 = 42380
- 193 + 42187 = 42380
- 199 + 42181 = 42380
Showing the first eight; more decompositions exist.
