Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83842, here are decompositions:
- 29 + 83813 = 83842
- 179 + 83663 = 83842
- 233 + 83609 = 83842
- 251 + 83591 = 83842
- 263 + 83579 = 83842
- 281 + 83561 = 83842
- 383 + 83459 = 83842
- 419 + 83423 = 83842
Showing the first eight; more decompositions exist.
