Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72408, here are decompositions:
- 29 + 72379 = 72408
- 41 + 72367 = 72408
- 67 + 72341 = 72408
- 71 + 72337 = 72408
- 101 + 72307 = 72408
- 131 + 72277 = 72408
- 137 + 72271 = 72408
- 139 + 72269 = 72408
Showing the first eight; more decompositions exist.
