Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002428, here are decompositions:
- 67 + 1002361 = 1002428
- 79 + 1002349 = 1002428
- 139 + 1002289 = 1002428
- 181 + 1002247 = 1002428
- 277 + 1002151 = 1002428
- 307 + 1002121 = 1002428
- 337 + 1002091 = 1002428
- 367 + 1002061 = 1002428
Showing the first eight; more decompositions exist.
