Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63988, here are decompositions:
- 11 + 63977 = 63988
- 59 + 63929 = 63988
- 131 + 63857 = 63988
- 149 + 63839 = 63988
- 179 + 63809 = 63988
- 227 + 63761 = 63988
- 251 + 63737 = 63988
- 269 + 63719 = 63988
Showing the first eight; more decompositions exist.
