Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42968, here are decompositions:
- 7 + 42961 = 42968
- 31 + 42937 = 42968
- 67 + 42901 = 42968
- 109 + 42859 = 42968
- 127 + 42841 = 42968
- 139 + 42829 = 42968
- 181 + 42787 = 42968
- 241 + 42727 = 42968
Showing the first eight; more decompositions exist.
