Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87154, here are decompositions:
- 3 + 87151 = 87154
- 5 + 87149 = 87154
- 47 + 87107 = 87154
- 71 + 87083 = 87154
- 83 + 87071 = 87154
- 113 + 87041 = 87154
- 173 + 86981 = 87154
- 227 + 86927 = 87154
Showing the first eight; more decompositions exist.
