Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1024128, here are decompositions:
- 29 + 1024099 = 1024128
- 37 + 1024091 = 1024128
- 41 + 1024087 = 1024128
- 67 + 1024061 = 1024128
- 97 + 1024031 = 1024128
- 107 + 1024021 = 1024128
- 137 + 1023991 = 1024128
- 151 + 1023977 = 1024128
Showing the first eight; more decompositions exist.
