Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23178, here are decompositions:
- 5 + 23173 = 23178
- 11 + 23167 = 23178
- 19 + 23159 = 23178
- 47 + 23131 = 23178
- 61 + 23117 = 23178
- 79 + 23099 = 23178
- 97 + 23081 = 23178
- 107 + 23071 = 23178
Showing the first eight; more decompositions exist.
