Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30792, here are decompositions:
- 11 + 30781 = 30792
- 19 + 30773 = 30792
- 29 + 30763 = 30792
- 79 + 30713 = 30792
- 89 + 30703 = 30792
- 103 + 30689 = 30792
- 131 + 30661 = 30792
- 149 + 30643 = 30792
Showing the first eight; more decompositions exist.
