Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30784, here are decompositions:
- 3 + 30781 = 30784
- 11 + 30773 = 30784
- 71 + 30713 = 30784
- 107 + 30677 = 30784
- 113 + 30671 = 30784
- 191 + 30593 = 30784
- 227 + 30557 = 30784
- 293 + 30491 = 30784
Showing the first eight; more decompositions exist.
