Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30998, here are decompositions:
- 61 + 30937 = 30998
- 67 + 30931 = 30998
- 127 + 30871 = 30998
- 139 + 30859 = 30998
- 157 + 30841 = 30998
- 181 + 30817 = 30998
- 241 + 30757 = 30998
- 271 + 30727 = 30998
Showing the first eight; more decompositions exist.
