Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82742, here are decompositions:
- 13 + 82729 = 82742
- 19 + 82723 = 82742
- 43 + 82699 = 82742
- 109 + 82633 = 82742
- 151 + 82591 = 82742
- 181 + 82561 = 82742
- 193 + 82549 = 82742
- 211 + 82531 = 82742
Showing the first eight; more decompositions exist.
