Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72126, here are decompositions:
- 17 + 72109 = 72126
- 23 + 72103 = 72126
- 37 + 72089 = 72126
- 53 + 72073 = 72126
- 73 + 72053 = 72126
- 79 + 72047 = 72126
- 83 + 72043 = 72126
- 107 + 72019 = 72126
Showing the first eight; more decompositions exist.
