Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028160, here are decompositions:
- 11 + 1028149 = 1028160
- 19 + 1028141 = 1028160
- 31 + 1028129 = 1028160
- 43 + 1028117 = 1028160
- 47 + 1028113 = 1028160
- 53 + 1028107 = 1028160
- 59 + 1028101 = 1028160
- 61 + 1028099 = 1028160
Showing the first eight; more decompositions exist.
