Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63868, here are decompositions:
- 5 + 63863 = 63868
- 11 + 63857 = 63868
- 29 + 63839 = 63868
- 59 + 63809 = 63868
- 107 + 63761 = 63868
- 131 + 63737 = 63868
- 149 + 63719 = 63868
- 179 + 63689 = 63868
Showing the first eight; more decompositions exist.
