Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012642, here are decompositions:
- 5 + 1012637 = 1012642
- 11 + 1012631 = 1012642
- 23 + 1012619 = 1012642
- 41 + 1012601 = 1012642
- 83 + 1012559 = 1012642
- 179 + 1012463 = 1012642
- 263 + 1012379 = 1012642
- 269 + 1012373 = 1012642
Showing the first eight; more decompositions exist.
