Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1050840, here are decompositions:
- 23 + 1050817 = 1050840
- 29 + 1050811 = 1050840
- 59 + 1050781 = 1050840
- 67 + 1050773 = 1050840
- 71 + 1050769 = 1050840
- 97 + 1050743 = 1050840
- 101 + 1050739 = 1050840
- 103 + 1050737 = 1050840
Showing the first eight; more decompositions exist.
