Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72456, here are decompositions:
- 73 + 72383 = 72456
- 89 + 72367 = 72456
- 103 + 72353 = 72456
- 149 + 72307 = 72456
- 179 + 72277 = 72456
- 227 + 72229 = 72456
- 229 + 72227 = 72456
- 233 + 72223 = 72456
Showing the first eight; more decompositions exist.
