Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72016, here are decompositions:
- 17 + 71999 = 72016
- 23 + 71993 = 72016
- 29 + 71987 = 72016
- 53 + 71963 = 72016
- 83 + 71933 = 72016
- 107 + 71909 = 72016
- 137 + 71879 = 72016
- 149 + 71867 = 72016
Showing the first eight; more decompositions exist.
