Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39928, here are decompositions:
- 41 + 39887 = 39928
- 59 + 39869 = 39928
- 71 + 39857 = 39928
- 89 + 39839 = 39928
- 101 + 39827 = 39928
- 107 + 39821 = 39928
- 137 + 39791 = 39928
- 149 + 39779 = 39928
Showing the first eight; more decompositions exist.
