Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30790, here are decompositions:
- 17 + 30773 = 30790
- 83 + 30707 = 30790
- 101 + 30689 = 30790
- 113 + 30677 = 30790
- 197 + 30593 = 30790
- 233 + 30557 = 30790
- 251 + 30539 = 30790
- 281 + 30509 = 30790
Showing the first eight; more decompositions exist.
