Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72192, here are decompositions:
- 19 + 72173 = 72192
- 23 + 72169 = 72192
- 31 + 72161 = 72192
- 53 + 72139 = 72192
- 83 + 72109 = 72192
- 89 + 72103 = 72192
- 101 + 72091 = 72192
- 103 + 72089 = 72192
Showing the first eight; more decompositions exist.
