Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51100, here are decompositions:
- 29 + 51071 = 51100
- 41 + 51059 = 51100
- 53 + 51047 = 51100
- 107 + 50993 = 51100
- 131 + 50969 = 51100
- 149 + 50951 = 51100
- 191 + 50909 = 51100
- 227 + 50873 = 51100
Showing the first eight; more decompositions exist.
