Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121264, here are decompositions:
- 5 + 121259 = 121264
- 83 + 121181 = 121264
- 107 + 121157 = 121264
- 113 + 121151 = 121264
- 197 + 121067 = 121264
- 251 + 121013 = 121264
- 257 + 121007 = 121264
- 263 + 121001 = 121264
Showing the first eight; more decompositions exist.
