Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11988, here are decompositions:
- 7 + 11981 = 11988
- 17 + 11971 = 11988
- 19 + 11969 = 11988
- 29 + 11959 = 11988
- 47 + 11941 = 11988
- 61 + 11927 = 11988
- 79 + 11909 = 11988
- 101 + 11887 = 11988
Showing the first eight; more decompositions exist.
