Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72120, here are decompositions:
- 11 + 72109 = 72120
- 17 + 72103 = 72120
- 19 + 72101 = 72120
- 29 + 72091 = 72120
- 31 + 72089 = 72120
- 43 + 72077 = 72120
- 47 + 72073 = 72120
- 67 + 72053 = 72120
Showing the first eight; more decompositions exist.
