Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63998, here are decompositions:
- 97 + 63901 = 63998
- 157 + 63841 = 63998
- 199 + 63799 = 63998
- 271 + 63727 = 63998
- 307 + 63691 = 63998
- 331 + 63667 = 63998
- 349 + 63649 = 63998
- 397 + 63601 = 63998
Showing the first eight; more decompositions exist.
