Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005078, here are decompositions:
- 5 + 1005073 = 1005078
- 7 + 1005071 = 1005078
- 29 + 1005049 = 1005078
- 37 + 1005041 = 1005078
- 59 + 1005019 = 1005078
- 71 + 1005007 = 1005078
- 97 + 1004981 = 1005078
- 101 + 1004977 = 1005078
Showing the first eight; more decompositions exist.
