Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121144, here are decompositions:
- 5 + 121139 = 121144
- 83 + 121061 = 121144
- 131 + 121013 = 121144
- 137 + 121007 = 121144
- 167 + 120977 = 121144
- 197 + 120947 = 121144
- 227 + 120917 = 121144
- 281 + 120863 = 121144
Showing the first eight; more decompositions exist.
