Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30996, here are decompositions:
- 13 + 30983 = 30996
- 19 + 30977 = 30996
- 47 + 30949 = 30996
- 59 + 30937 = 30996
- 103 + 30893 = 30996
- 127 + 30869 = 30996
- 137 + 30859 = 30996
- 157 + 30839 = 30996
Showing the first eight; more decompositions exist.
