Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30968, here are decompositions:
- 19 + 30949 = 30968
- 31 + 30937 = 30968
- 37 + 30931 = 30968
- 97 + 30871 = 30968
- 109 + 30859 = 30968
- 127 + 30841 = 30968
- 139 + 30829 = 30968
- 151 + 30817 = 30968
Showing the first eight; more decompositions exist.
