Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72396, here are decompositions:
- 13 + 72383 = 72396
- 17 + 72379 = 72396
- 29 + 72367 = 72396
- 43 + 72353 = 72396
- 59 + 72337 = 72396
- 83 + 72313 = 72396
- 89 + 72307 = 72396
- 109 + 72287 = 72396
Showing the first eight; more decompositions exist.
