Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72450, here are decompositions:
- 19 + 72431 = 72450
- 29 + 72421 = 72450
- 67 + 72383 = 72450
- 71 + 72379 = 72450
- 83 + 72367 = 72450
- 97 + 72353 = 72450
- 109 + 72341 = 72450
- 113 + 72337 = 72450
Showing the first eight; more decompositions exist.
