Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 63886, here are decompositions:
- 23 + 63863 = 63886
- 29 + 63857 = 63886
- 47 + 63839 = 63886
- 83 + 63803 = 63886
- 113 + 63773 = 63886
- 149 + 63737 = 63886
- 167 + 63719 = 63886
- 197 + 63689 = 63886
Showing the first eight; more decompositions exist.
