Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72118, here are decompositions:
- 17 + 72101 = 72118
- 29 + 72089 = 72118
- 41 + 72077 = 72118
- 71 + 72047 = 72118
- 131 + 71987 = 72118
- 239 + 71879 = 72118
- 251 + 71867 = 72118
- 257 + 71861 = 72118
Showing the first eight; more decompositions exist.
