Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72202, here are decompositions:
- 29 + 72173 = 72202
- 41 + 72161 = 72202
- 101 + 72101 = 72202
- 113 + 72089 = 72202
- 149 + 72053 = 72202
- 239 + 71963 = 72202
- 269 + 71933 = 72202
- 293 + 71909 = 72202
Showing the first eight; more decompositions exist.
