Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39904, here are decompositions:
- 3 + 39901 = 39904
- 17 + 39887 = 39904
- 41 + 39863 = 39904
- 47 + 39857 = 39904
- 83 + 39821 = 39904
- 113 + 39791 = 39904
- 233 + 39671 = 39904
- 281 + 39623 = 39904
Showing the first eight; more decompositions exist.
