Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56138, here are decompositions:
- 7 + 56131 = 56138
- 37 + 56101 = 56138
- 97 + 56041 = 56138
- 151 + 55987 = 56138
- 211 + 55927 = 56138
- 241 + 55897 = 56138
- 331 + 55807 = 56138
- 421 + 55717 = 56138
Showing the first eight; more decompositions exist.
