Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81746, here are decompositions:
- 19 + 81727 = 81746
- 43 + 81703 = 81746
- 79 + 81667 = 81746
- 97 + 81649 = 81746
- 109 + 81637 = 81746
- 127 + 81619 = 81746
- 193 + 81553 = 81746
- 199 + 81547 = 81746
Showing the first eight; more decompositions exist.
