Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81762, here are decompositions:
- 13 + 81749 = 81762
- 59 + 81703 = 81762
- 61 + 81701 = 81762
- 73 + 81689 = 81762
- 113 + 81649 = 81762
- 151 + 81611 = 81762
- 193 + 81569 = 81762
- 199 + 81563 = 81762
Showing the first eight; more decompositions exist.
