Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72390, here are decompositions:
- 7 + 72383 = 72390
- 11 + 72379 = 72390
- 23 + 72367 = 72390
- 37 + 72353 = 72390
- 53 + 72337 = 72390
- 83 + 72307 = 72390
- 103 + 72287 = 72390
- 113 + 72277 = 72390
Showing the first eight; more decompositions exist.
