Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39894, here are decompositions:
- 7 + 39887 = 39894
- 11 + 39883 = 39894
- 17 + 39877 = 39894
- 31 + 39863 = 39894
- 37 + 39857 = 39894
- 47 + 39847 = 39894
- 53 + 39841 = 39894
- 67 + 39827 = 39894
Showing the first eight; more decompositions exist.
