Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7968, here are decompositions:
- 5 + 7963 = 7968
- 17 + 7951 = 7968
- 19 + 7949 = 7968
- 31 + 7937 = 7968
- 41 + 7927 = 7968
- 61 + 7907 = 7968
- 67 + 7901 = 7968
- 89 + 7879 = 7968
Showing the first eight; more decompositions exist.
