Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1052128, here are decompositions:
- 17 + 1052111 = 1052128
- 29 + 1052099 = 1052128
- 89 + 1052039 = 1052128
- 101 + 1052027 = 1052128
- 137 + 1051991 = 1052128
- 149 + 1051979 = 1052128
- 167 + 1051961 = 1052128
- 179 + 1051949 = 1052128
Showing the first eight; more decompositions exist.
