Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005444, here are decompositions:
- 5 + 1005439 = 1005444
- 7 + 1005437 = 1005444
- 17 + 1005427 = 1005444
- 31 + 1005413 = 1005444
- 53 + 1005391 = 1005444
- 71 + 1005373 = 1005444
- 73 + 1005371 = 1005444
- 113 + 1005331 = 1005444
Showing the first eight; more decompositions exist.
