Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63986, here are decompositions:
- 37 + 63949 = 63986
- 73 + 63913 = 63986
- 79 + 63907 = 63986
- 163 + 63823 = 63986
- 193 + 63793 = 63986
- 277 + 63709 = 63986
- 283 + 63703 = 63986
- 337 + 63649 = 63986
Showing the first eight; more decompositions exist.
