Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121164, here are decompositions:
- 7 + 121157 = 121164
- 13 + 121151 = 121164
- 41 + 121123 = 121164
- 83 + 121081 = 121164
- 97 + 121067 = 121164
- 101 + 121063 = 121164
- 103 + 121061 = 121164
- 151 + 121013 = 121164
Showing the first eight; more decompositions exist.
