Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018368, here are decompositions:
- 11 + 1018357 = 1018368
- 31 + 1018337 = 1018368
- 59 + 1018309 = 1018368
- 67 + 1018301 = 1018368
- 97 + 1018271 = 1018368
- 151 + 1018217 = 1018368
- 167 + 1018201 = 1018368
- 191 + 1018177 = 1018368
Showing the first eight; more decompositions exist.
