Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39964, here are decompositions:
- 11 + 39953 = 39964
- 101 + 39863 = 39964
- 107 + 39857 = 39964
- 137 + 39827 = 39964
- 173 + 39791 = 39964
- 293 + 39671 = 39964
- 383 + 39581 = 39964
- 401 + 39563 = 39964
Showing the first eight; more decompositions exist.
