Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39946, here are decompositions:
- 17 + 39929 = 39946
- 59 + 39887 = 39946
- 83 + 39863 = 39946
- 89 + 39857 = 39946
- 107 + 39839 = 39946
- 167 + 39779 = 39946
- 197 + 39749 = 39946
- 227 + 39719 = 39946
Showing the first eight; more decompositions exist.
