Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3936, here are decompositions:
- 5 + 3931 = 3936
- 7 + 3929 = 3936
- 13 + 3923 = 3936
- 17 + 3919 = 3936
- 19 + 3917 = 3936
- 29 + 3907 = 3936
- 47 + 3889 = 3936
- 59 + 3877 = 3936
Showing the first eight; more decompositions exist.
