Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39742, here are decompositions:
- 23 + 39719 = 39742
- 71 + 39671 = 39742
- 83 + 39659 = 39742
- 173 + 39569 = 39742
- 179 + 39563 = 39742
- 191 + 39551 = 39742
- 233 + 39509 = 39742
- 239 + 39503 = 39742
Showing the first eight; more decompositions exist.
