Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121996, here are decompositions:
- 3 + 121993 = 121996
- 29 + 121967 = 121996
- 47 + 121949 = 121996
- 59 + 121937 = 121996
- 107 + 121889 = 121996
- 113 + 121883 = 121996
- 233 + 121763 = 121996
- 269 + 121727 = 121996
Showing the first eight; more decompositions exist.
