Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028874, here are decompositions:
- 31 + 1028843 = 1028874
- 37 + 1028837 = 1028874
- 71 + 1028803 = 1028874
- 97 + 1028777 = 1028874
- 101 + 1028773 = 1028874
- 113 + 1028761 = 1028874
- 127 + 1028747 = 1028874
- 137 + 1028737 = 1028874
Showing the first eight; more decompositions exist.
