Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51888, here are decompositions:
- 17 + 51871 = 51888
- 19 + 51869 = 51888
- 29 + 51859 = 51888
- 59 + 51829 = 51888
- 61 + 51827 = 51888
- 71 + 51817 = 51888
- 101 + 51787 = 51888
- 139 + 51749 = 51888
Showing the first eight; more decompositions exist.
