Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12006, here are decompositions:
- 19 + 11987 = 12006
- 37 + 11969 = 12006
- 47 + 11959 = 12006
- 53 + 11953 = 12006
- 67 + 11939 = 12006
- 73 + 11933 = 12006
- 79 + 11927 = 12006
- 83 + 11923 = 12006
Showing the first eight; more decompositions exist.
