Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72398, here are decompositions:
- 19 + 72379 = 72398
- 31 + 72367 = 72398
- 61 + 72337 = 72398
- 127 + 72271 = 72398
- 229 + 72169 = 72398
- 307 + 72091 = 72398
- 367 + 72031 = 72398
- 379 + 72019 = 72398
Showing the first eight; more decompositions exist.
