Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1043120, here are decompositions:
- 3 + 1043117 = 1043120
- 7 + 1043113 = 1043120
- 31 + 1043089 = 1043120
- 37 + 1043083 = 1043120
- 73 + 1043047 = 1043120
- 97 + 1043023 = 1043120
- 109 + 1043011 = 1043120
- 223 + 1042897 = 1043120
Showing the first eight; more decompositions exist.
