Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81734, here are decompositions:
- 7 + 81727 = 81734
- 31 + 81703 = 81734
- 67 + 81667 = 81734
- 97 + 81637 = 81734
- 181 + 81553 = 81734
- 271 + 81463 = 81734
- 277 + 81457 = 81734
- 313 + 81421 = 81734
Showing the first eight; more decompositions exist.
