Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81176, here are decompositions:
- 3 + 81173 = 81176
- 13 + 81163 = 81176
- 19 + 81157 = 81176
- 79 + 81097 = 81176
- 127 + 81049 = 81176
- 157 + 81019 = 81176
- 163 + 81013 = 81176
- 223 + 80953 = 81176
Showing the first eight; more decompositions exist.
