Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39966, here are decompositions:
- 13 + 39953 = 39966
- 29 + 39937 = 39966
- 37 + 39929 = 39966
- 79 + 39887 = 39966
- 83 + 39883 = 39966
- 89 + 39877 = 39966
- 97 + 39869 = 39966
- 103 + 39863 = 39966
Showing the first eight; more decompositions exist.
