Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51880, here are decompositions:
- 11 + 51869 = 51880
- 41 + 51839 = 51880
- 53 + 51827 = 51880
- 83 + 51797 = 51880
- 113 + 51767 = 51880
- 131 + 51749 = 51880
- 167 + 51713 = 51880
- 197 + 51683 = 51880
Showing the first eight; more decompositions exist.
