Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 968, here are decompositions:
- 31 + 937 = 968
- 61 + 907 = 968
- 109 + 859 = 968
- 139 + 829 = 968
- 157 + 811 = 968
- 181 + 787 = 968
- 199 + 769 = 968
- 211 + 757 = 968
Showing the first eight; more decompositions exist.
