Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54240, here are decompositions:
- 23 + 54217 = 54240
- 47 + 54193 = 54240
- 59 + 54181 = 54240
- 73 + 54167 = 54240
- 89 + 54151 = 54240
- 101 + 54139 = 54240
- 107 + 54133 = 54240
- 139 + 54101 = 54240
Showing the first eight; more decompositions exist.
