Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027488, here are decompositions:
- 5 + 1027483 = 1027488
- 17 + 1027471 = 1027488
- 29 + 1027459 = 1027488
- 61 + 1027427 = 1027488
- 67 + 1027421 = 1027488
- 71 + 1027417 = 1027488
- 79 + 1027409 = 1027488
- 97 + 1027391 = 1027488
Showing the first eight; more decompositions exist.
