Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72468, here are decompositions:
- 7 + 72461 = 72468
- 37 + 72431 = 72468
- 47 + 72421 = 72468
- 89 + 72379 = 72468
- 101 + 72367 = 72468
- 127 + 72341 = 72468
- 131 + 72337 = 72468
- 181 + 72287 = 72468
Showing the first eight; more decompositions exist.
