Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81752, here are decompositions:
- 3 + 81749 = 81752
- 103 + 81649 = 81752
- 193 + 81559 = 81752
- 199 + 81553 = 81752
- 313 + 81439 = 81752
- 331 + 81421 = 81752
- 379 + 81373 = 81752
- 409 + 81343 = 81752
Showing the first eight; more decompositions exist.
