Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39824, here are decompositions:
- 3 + 39821 = 39824
- 97 + 39727 = 39824
- 157 + 39667 = 39824
- 193 + 39631 = 39824
- 283 + 39541 = 39824
- 313 + 39511 = 39824
- 373 + 39451 = 39824
- 457 + 39367 = 39824
Showing the first eight; more decompositions exist.
