Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020864, here are decompositions:
- 11 + 1020853 = 1020864
- 17 + 1020847 = 1020864
- 23 + 1020841 = 1020864
- 37 + 1020827 = 1020864
- 41 + 1020823 = 1020864
- 43 + 1020821 = 1020864
- 67 + 1020797 = 1020864
- 107 + 1020757 = 1020864
Showing the first eight; more decompositions exist.
