Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11982, here are decompositions:
- 11 + 11971 = 11982
- 13 + 11969 = 11982
- 23 + 11959 = 11982
- 29 + 11953 = 11982
- 41 + 11941 = 11982
- 43 + 11939 = 11982
- 59 + 11923 = 11982
- 73 + 11909 = 11982
Showing the first eight; more decompositions exist.
