Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30922, here are decompositions:
- 11 + 30911 = 30922
- 29 + 30893 = 30922
- 41 + 30881 = 30922
- 53 + 30869 = 30922
- 71 + 30851 = 30922
- 83 + 30839 = 30922
- 113 + 30809 = 30922
- 149 + 30773 = 30922
Showing the first eight; more decompositions exist.
