Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72116, here are decompositions:
- 7 + 72109 = 72116
- 13 + 72103 = 72116
- 43 + 72073 = 72116
- 73 + 72043 = 72116
- 97 + 72019 = 72116
- 199 + 71917 = 72116
- 229 + 71887 = 72116
- 307 + 71809 = 72116
Showing the first eight; more decompositions exist.
