Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38808, here are decompositions:
- 5 + 38803 = 38808
- 17 + 38791 = 38808
- 41 + 38767 = 38808
- 59 + 38749 = 38808
- 61 + 38747 = 38808
- 71 + 38737 = 38808
- 79 + 38729 = 38808
- 97 + 38711 = 38808
Showing the first eight; more decompositions exist.
