Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39856, here are decompositions:
- 17 + 39839 = 39856
- 29 + 39827 = 39856
- 107 + 39749 = 39856
- 137 + 39719 = 39856
- 197 + 39659 = 39856
- 233 + 39623 = 39856
- 293 + 39563 = 39856
- 347 + 39509 = 39856
Showing the first eight; more decompositions exist.
