Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024920, here are decompositions:
- 11 + 1024909 = 1024920
- 19 + 1024901 = 1024920
- 37 + 1024883 = 1024920
- 67 + 1024853 = 1024920
- 97 + 1024823 = 1024920
- 137 + 1024783 = 1024920
- 163 + 1024757 = 1024920
- 191 + 1024729 = 1024920
Showing the first eight; more decompositions exist.
