Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121068, here are decompositions:
- 5 + 121063 = 121068
- 7 + 121061 = 121068
- 29 + 121039 = 121068
- 47 + 121021 = 121068
- 61 + 121007 = 121068
- 67 + 121001 = 121068
- 71 + 120997 = 121068
- 127 + 120941 = 121068
Showing the first eight; more decompositions exist.
