Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30970, here are decompositions:
- 29 + 30941 = 30970
- 59 + 30911 = 30970
- 89 + 30881 = 30970
- 101 + 30869 = 30970
- 131 + 30839 = 30970
- 167 + 30803 = 30970
- 197 + 30773 = 30970
- 257 + 30713 = 30970
Showing the first eight; more decompositions exist.
