Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 54180, here are decompositions:
- 13 + 54167 = 54180
- 17 + 54163 = 54180
- 29 + 54151 = 54180
- 41 + 54139 = 54180
- 47 + 54133 = 54180
- 59 + 54121 = 54180
- 79 + 54101 = 54180
- 89 + 54091 = 54180
Showing the first eight; more decompositions exist.
