Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39804, here are decompositions:
- 5 + 39799 = 39804
- 13 + 39791 = 39804
- 43 + 39761 = 39804
- 71 + 39733 = 39804
- 101 + 39703 = 39804
- 137 + 39667 = 39804
- 173 + 39631 = 39804
- 181 + 39623 = 39804
Showing the first eight; more decompositions exist.
