Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82770, here are decompositions:
- 7 + 82763 = 82770
- 11 + 82759 = 82770
- 13 + 82757 = 82770
- 41 + 82729 = 82770
- 43 + 82727 = 82770
- 47 + 82723 = 82770
- 71 + 82699 = 82770
- 113 + 82657 = 82770
Showing the first eight; more decompositions exist.
