Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39984, here are decompositions:
- 5 + 39979 = 39984
- 13 + 39971 = 39984
- 31 + 39953 = 39984
- 47 + 39937 = 39984
- 83 + 39901 = 39984
- 97 + 39887 = 39984
- 101 + 39883 = 39984
- 107 + 39877 = 39984
Showing the first eight; more decompositions exist.
