Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30748, here are decompositions:
- 41 + 30707 = 30748
- 59 + 30689 = 30748
- 71 + 30677 = 30748
- 191 + 30557 = 30748
- 239 + 30509 = 30748
- 251 + 30497 = 30748
- 257 + 30491 = 30748
- 281 + 30467 = 30748
Showing the first eight; more decompositions exist.
