Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30880, here are decompositions:
- 11 + 30869 = 30880
- 29 + 30851 = 30880
- 41 + 30839 = 30880
- 71 + 30809 = 30880
- 107 + 30773 = 30880
- 167 + 30713 = 30880
- 173 + 30707 = 30880
- 191 + 30689 = 30880
Showing the first eight; more decompositions exist.
