Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30946, here are decompositions:
- 5 + 30941 = 30946
- 53 + 30893 = 30946
- 107 + 30839 = 30946
- 137 + 30809 = 30946
- 173 + 30773 = 30946
- 233 + 30713 = 30946
- 239 + 30707 = 30946
- 257 + 30689 = 30946
Showing the first eight; more decompositions exist.
