Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30768, here are decompositions:
- 5 + 30763 = 30768
- 11 + 30757 = 30768
- 41 + 30727 = 30768
- 61 + 30707 = 30768
- 71 + 30697 = 30768
- 79 + 30689 = 30768
- 97 + 30671 = 30768
- 107 + 30661 = 30768
Showing the first eight; more decompositions exist.
