Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005342, here are decompositions:
- 11 + 1005331 = 1005342
- 29 + 1005313 = 1005342
- 73 + 1005269 = 1005342
- 101 + 1005241 = 1005342
- 103 + 1005239 = 1005342
- 113 + 1005229 = 1005342
- 139 + 1005203 = 1005342
- 181 + 1005161 = 1005342
Showing the first eight; more decompositions exist.
