Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11880, here are decompositions:
- 13 + 11867 = 11880
- 17 + 11863 = 11880
- 41 + 11839 = 11880
- 47 + 11833 = 11880
- 53 + 11827 = 11880
- 59 + 11821 = 11880
- 67 + 11813 = 11880
- 73 + 11807 = 11880
Showing the first eight; more decompositions exist.
