Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009942, here are decompositions:
- 5 + 1009937 = 1009942
- 41 + 1009901 = 1009942
- 83 + 1009859 = 1009942
- 293 + 1009649 = 1009942
- 383 + 1009559 = 1009942
- 443 + 1009499 = 1009942
- 503 + 1009439 = 1009942
- 509 + 1009433 = 1009942
Showing the first eight; more decompositions exist.
