Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027180, here are decompositions:
- 17 + 1027163 = 1027180
- 41 + 1027139 = 1027180
- 53 + 1027127 = 1027180
- 83 + 1027097 = 1027180
- 113 + 1027067 = 1027180
- 149 + 1027031 = 1027180
- 179 + 1027001 = 1027180
- 191 + 1026989 = 1027180
Showing the first eight; more decompositions exist.
