Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005186, here are decompositions:
- 43 + 1005143 = 1005186
- 53 + 1005133 = 1005186
- 79 + 1005107 = 1005186
- 107 + 1005079 = 1005186
- 113 + 1005073 = 1005186
- 137 + 1005049 = 1005186
- 157 + 1005029 = 1005186
- 167 + 1005019 = 1005186
Showing the first eight; more decompositions exist.
