Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11842, here are decompositions:
- 3 + 11839 = 11842
- 11 + 11831 = 11842
- 29 + 11813 = 11842
- 41 + 11801 = 11842
- 53 + 11789 = 11842
- 59 + 11783 = 11842
- 263 + 11579 = 11842
- 293 + 11549 = 11842
Showing the first eight; more decompositions exist.
