Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71936, here are decompositions:
- 3 + 71933 = 71936
- 19 + 71917 = 71936
- 37 + 71899 = 71936
- 127 + 71809 = 71936
- 223 + 71713 = 71936
- 229 + 71707 = 71936
- 367 + 71569 = 71936
- 373 + 71563 = 71936
Showing the first eight; more decompositions exist.
