Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005402, here are decompositions:
- 11 + 1005391 = 1005402
- 29 + 1005373 = 1005402
- 31 + 1005371 = 1005402
- 43 + 1005359 = 1005402
- 53 + 1005349 = 1005402
- 71 + 1005331 = 1005402
- 89 + 1005313 = 1005402
- 109 + 1005293 = 1005402
Showing the first eight; more decompositions exist.
