Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42356, here are decompositions:
- 7 + 42349 = 42356
- 19 + 42337 = 42356
- 73 + 42283 = 42356
- 163 + 42193 = 42356
- 199 + 42157 = 42356
- 283 + 42073 = 42356
- 313 + 42043 = 42356
- 337 + 42019 = 42356
Showing the first eight; more decompositions exist.
