Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39008, here are decompositions:
- 31 + 38977 = 39008
- 37 + 38971 = 39008
- 157 + 38851 = 39008
- 241 + 38767 = 39008
- 271 + 38737 = 39008
- 331 + 38677 = 39008
- 337 + 38671 = 39008
- 379 + 38629 = 39008
Showing the first eight; more decompositions exist.
