Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86928, here are decompositions:
- 5 + 86923 = 86928
- 59 + 86869 = 86928
- 67 + 86861 = 86928
- 71 + 86857 = 86928
- 157 + 86771 = 86928
- 199 + 86729 = 86928
- 239 + 86689 = 86928
- 251 + 86677 = 86928
Showing the first eight; more decompositions exist.
