Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12008, here are decompositions:
- 37 + 11971 = 12008
- 67 + 11941 = 12008
- 181 + 11827 = 12008
- 229 + 11779 = 12008
- 277 + 11731 = 12008
- 307 + 11701 = 12008
- 331 + 11677 = 12008
- 421 + 11587 = 12008
Showing the first eight; more decompositions exist.
