Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11830, here are decompositions:
- 3 + 11827 = 11830
- 17 + 11813 = 11830
- 23 + 11807 = 11830
- 29 + 11801 = 11830
- 41 + 11789 = 11830
- 47 + 11783 = 11830
- 53 + 11777 = 11830
- 113 + 11717 = 11830
Showing the first eight; more decompositions exist.
