Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123966, here are decompositions:
- 13 + 123953 = 123966
- 43 + 123923 = 123966
- 79 + 123887 = 123966
- 103 + 123863 = 123966
- 113 + 123853 = 123966
- 137 + 123829 = 123966
- 149 + 123817 = 123966
- 163 + 123803 = 123966
Showing the first eight; more decompositions exist.
