Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51146, here are decompositions:
- 13 + 51133 = 51146
- 37 + 51109 = 51146
- 103 + 51043 = 51146
- 157 + 50989 = 51146
- 223 + 50923 = 51146
- 307 + 50839 = 51146
- 313 + 50833 = 51146
- 373 + 50773 = 51146
Showing the first eight; more decompositions exist.
