Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42694, here are decompositions:
- 5 + 42689 = 42694
- 11 + 42683 = 42694
- 17 + 42677 = 42694
- 53 + 42641 = 42694
- 83 + 42611 = 42694
- 137 + 42557 = 42694
- 227 + 42467 = 42694
- 233 + 42461 = 42694
Showing the first eight; more decompositions exist.
