Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86880, here are decompositions:
- 11 + 86869 = 86880
- 19 + 86861 = 86880
- 23 + 86857 = 86880
- 29 + 86851 = 86880
- 37 + 86843 = 86880
- 43 + 86837 = 86880
- 67 + 86813 = 86880
- 97 + 86783 = 86880
Showing the first eight; more decompositions exist.
