Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045320, here are decompositions:
- 11 + 1045309 = 1045320
- 13 + 1045307 = 1045320
- 43 + 1045277 = 1045320
- 47 + 1045273 = 1045320
- 79 + 1045241 = 1045320
- 83 + 1045237 = 1045320
- 97 + 1045223 = 1045320
- 127 + 1045193 = 1045320
Showing the first eight; more decompositions exist.
