Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13008, here are decompositions:
- 5 + 13003 = 13008
- 7 + 13001 = 13008
- 29 + 12979 = 13008
- 41 + 12967 = 13008
- 67 + 12941 = 13008
- 89 + 12919 = 13008
- 97 + 12911 = 13008
- 101 + 12907 = 13008
Showing the first eight; more decompositions exist.
