Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72188, here are decompositions:
- 19 + 72169 = 72188
- 79 + 72109 = 72188
- 97 + 72091 = 72188
- 157 + 72031 = 72188
- 241 + 71947 = 72188
- 271 + 71917 = 72188
- 307 + 71881 = 72188
- 367 + 71821 = 72188
Showing the first eight; more decompositions exist.
