Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11998, here are decompositions:
- 11 + 11987 = 11998
- 17 + 11981 = 11998
- 29 + 11969 = 11998
- 59 + 11939 = 11998
- 71 + 11927 = 11998
- 89 + 11909 = 11998
- 101 + 11897 = 11998
- 131 + 11867 = 11998
Showing the first eight; more decompositions exist.
