Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72194, here are decompositions:
- 103 + 72091 = 72194
- 151 + 72043 = 72194
- 163 + 72031 = 72194
- 211 + 71983 = 72194
- 223 + 71971 = 72194
- 277 + 71917 = 72194
- 307 + 71887 = 72194
- 313 + 71881 = 72194
Showing the first eight; more decompositions exist.
