Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81794, here are decompositions:
- 67 + 81727 = 81794
- 127 + 81667 = 81794
- 157 + 81637 = 81794
- 241 + 81553 = 81794
- 277 + 81517 = 81794
- 331 + 81463 = 81794
- 337 + 81457 = 81794
- 373 + 81421 = 81794
Showing the first eight; more decompositions exist.
