Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81496, here are decompositions:
- 137 + 81359 = 81496
- 197 + 81299 = 81496
- 257 + 81239 = 81496
- 263 + 81233 = 81496
- 293 + 81203 = 81496
- 419 + 81077 = 81496
- 449 + 81047 = 81496
- 479 + 81017 = 81496
Showing the first eight; more decompositions exist.
