Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005488, here are decompositions:
- 7 + 1005481 = 1005488
- 31 + 1005457 = 1005488
- 61 + 1005427 = 1005488
- 79 + 1005409 = 1005488
- 97 + 1005391 = 1005488
- 139 + 1005349 = 1005488
- 157 + 1005331 = 1005488
- 271 + 1005217 = 1005488
Showing the first eight; more decompositions exist.
