Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30706, here are decompositions:
- 3 + 30703 = 30706
- 17 + 30689 = 30706
- 29 + 30677 = 30706
- 113 + 30593 = 30706
- 149 + 30557 = 30706
- 167 + 30539 = 30706
- 197 + 30509 = 30706
- 239 + 30467 = 30706
Showing the first eight; more decompositions exist.
