Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009856, here are decompositions:
- 13 + 1009843 = 1009856
- 19 + 1009837 = 1009856
- 37 + 1009819 = 1009856
- 109 + 1009747 = 1009856
- 229 + 1009627 = 1009856
- 283 + 1009573 = 1009856
- 349 + 1009507 = 1009856
- 373 + 1009483 = 1009856
Showing the first eight; more decompositions exist.
