Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30976, here are decompositions:
- 5 + 30971 = 30976
- 83 + 30893 = 30976
- 107 + 30869 = 30976
- 137 + 30839 = 30976
- 167 + 30809 = 30976
- 173 + 30803 = 30976
- 263 + 30713 = 30976
- 269 + 30707 = 30976
Showing the first eight; more decompositions exist.
